Stitches On Lower Right Abdominal

I have experienced it once on 1 trimester as well yes yesterday (2 trimester now) and both times I was told is due to uterus is stretching but what I noticed is that it was both time when I haven’t had my poop yet and the pain was gone once gods of constipation finally let it go. So I hope that it was that pressure that caused that needle pain (it was on the left side though for me) but of course it can be very individual. As long as no discharge or worse pain should be fine.
