Hi and Congrats!
I think we are in the same belly buddies group!
I have also been having period-type pains. They started when i was about 3w3d and were quite bad for a few days. I also had some stitch pain, especially on the left side. I went to the Dr and he sent me for a hcg test to make sure levels were rising as they should, which they are. I have also done quite a bit of research on it and it turns out it is VERY normal to experience this type of pain. Obviously is it gets worse or is associated with bleeding, then head straight to the Dr but please don't worry yourself about it as stress is NOT GOOD for you right now! This is my second bub and this pregnancy is already feeling completely different to my first! Lots of funny pains going on! Almost feels like butterflies are fluttering around in my uterus! Very strange feeling!
Goodluck!!!
Look forward to sharing this wonderful experience with you!
