- Number of diagnosed infections in pregnant women [ Time Frame: up to 12 weeks ]This includes any viral, bacterial and fungal infection (e.g. bacterial vaginosis, candidiasis, urinary tract infection, mastitis, cold, flu, gingivitis, etc.). A vaginal swab and saliva sample will be taken at every visit on site throughout pregnancy. The vaginal swab will be used for the detection of Bacterial Vaginosis and Candidiasis. Other required swab samples will be collected if an infection occurs (e.g. vaginal, mouth, throat, nose, etc.). If an infection is suspected by a participant in-between a scheduled visit, the participant will come on site to be checked by a doctor. If the participant is subsequently diagnosed with an infection, a saliva sample will need to be taken at this time.
- Levels of glucose, insulin, triglycerides and iron [ Time Frame: Measured 2 times up to 12 weeks ]Assessed via blood sample throughout the pregnancy
- Vaginal mycobiota [ Time Frame: Measured 3 times up to 18 weeks ]Vaginal microbiome which includes bacteria, fungus and potentially other eukaryotic micro-organisms such as parasites or viruses. To be assessed with a vaginal swab during pregnancy and after delivery.
- Inflammatory markers [ Time Frame: Measured up to 3 times in the 18 week time frame ]Assessing levels of both pro- and anti- inflammatory markers in the mother during pregnancy (through stool and blood samples) and after delivery (through breast milk sample).
- Vaginal microbiota [ Time Frame: Measured 3 times up to 18 weeks ]Effects of the probiotic interventions on overall microbiota composition in the mother will be assessed. In addition, recovery of the probiotic strains in the vaginal samples will be assessed.
- Premature rupture of membranes (PROM) [ Time Frame: Measured 1 time at week 12 ]Incidence of PROM on the probiotic versus the group
- Levels of secretory immunoglobulin A (sIgA) in the mother [ Time Frame: Measured up to 4 times in the 18 week time frame ]Assessed via saliva samples throughout pregnancy and a breast milk sample after delivery.
- Levels of secretory immunoglobulin A (sIgA) in the infant [ Time Frame: Measured 1 time up to18 weeks ]Assessed via stool sample after birth.
- Gut microbiota in the mother [ Time Frame: Measured 3 times up to 18 weeks ]Effects of the probiotic interventions on overall microbiota composition will be assessed. In addition, recovery of the probiotic strains in the stool samples will be assessed.
- Gut microbiota in the infant [ Time Frame: Measured 1 time up to 18 weeks ]Effects of the probiotic interventions on overall microbiota composition will be assessed. In addition, recovery of the probiotic strains in the stool samples will be assessed.
- Stool frequency and consistency in the mother [ Time Frame: Self-reported, daily up to 18 weeks ]Assessed with the Bristol Stool Scale
- Stool frequency and pattern in the infant [ Time Frame: Self-reported by the mother, daily up to 4-6 weeks ]Assessed with the Amsterdam Infant Stool Scale
- Weight in the mother [ Time Frame: Measured 3 times up to 18 weeks. Pre-pregnancy weight will also be noted via information collection on a demographic questionnaire. ]To assess change in body weight
- Breast milk microbiota [ Time Frame: Measured 1 time up to 18 weeks ]Effects of the probiotic interventions on overall microbiota composition will be assessed. In addition, recovery of the probiotic strains in the breast milk samples will be assessed.
- Post-Partum Depression [ Time Frame: Measured 2 time up to 18 weeks ]To be assessed with the Edinburgh Postnatal Depression Scale
- Infant's health status - NEC [ Time Frame: Measured 1 time up to 18 weeks. ]To assess the probability of an infant with NEC
- Anthropometric measurements [ Time Frame: Measured 1 time up to 18 weeks. The infant's anthropometric measurements at birth will also be noted. ]Crown-heel length and head circumference
- Weight in the infant [ Time Frame: Measured 2 times up to 18 weeks. ]To assess change in body weight
- Crying time in the infant [ Time Frame: Self-reported by the mother, daily up to 4-6 weeks ]To assess the mean daily crying time of infants
- Colic in the infant [ Time Frame: Self-reported by the mother, daily up to 4-6 weeks ]To asses the probability of an infant with colic
- Sleep in the infant [ Time Frame: Self-reported by the mother, daily up to 4-6 weeks ]Number of total hours and number of consecutive hours
- Number of infections [ Time Frame: Self-reported by the mother, daily up to 4-6 weeks ]To assess the number of infections
- Skin diseases or conditions [ Time Frame: 1 year follow up phone call ]Skin diseases/conditions as well as the child's overall health status 1 year after birth will be assessed.
- Infant's health status - jaundice [ Time Frame: Measured 1 time up to 18 weeks. ]To assess the probability of an infant with jaundice
- Infant's health status - Hyperbilirubinemia [ Time Frame: Measured 1 time up to 18 weeks. ]To assess the probability of an infant with Hyperbilirubinemia
