Wanted to write a post yesterday, forgot! Just saw a similar one now. We've been breastfeeding since birth, started giving Lactiline at 2 months old, no monthly bleeding, everything is fine. But yesterday and today (only during the day) my stomach hurts, it feels like a dull ache. The bra strap comes off easily and only slightly stains brown, then red, just barely. I have an ultrasound scheduled for Saturday, but can't go earlier. What could this be? Maybe a side effect from the medication? ??‍♀️
