Ok so this morning around 5- 6 am I started stomach pains . I thought it was a cramp since I was on my period, but the pain felt different from a cramp and I felt like I needed to vomit. So I thought maybe if i pass gass it could relieve the pain, but it didn't really help so I went to the bathroom and I sat on the toilet for a while nothing came out. So I decided to take a shower but the pain was still there. I ended my period today also but my stomach still hurts just not as bad as earlier in the day. So can someone help figure out if it constipation or something different im confused?.
