@Lynn thank you!
Hey, I also had this period like cramps but was told it was very likely from the uterus growing and expanding. I got them from around 6-10 weeks.. still occasionally get a twinge. Another Dr told me it can also be your ligaments stretching but I’m pretty sure it was the former.
Try prune juice for constipation, worked wonders for me. And cramps are normal. If it is combined with bleeding or pain to the point you’re crying > then get it checked. But strong period like pain is normal. I specifically had it in week 6 and 7 actually, all is well with baby
