Hi ladies

I'm 7.5 weeks along and started having bad stomach pains every night, not long after I go to bed. The last 3-4 nights. It doesn't seem to matter what time either as I went to bed very late last night and it didnt happen around 10:30 when I normally go, it happened about 12:45, about 15 min after I went.

It's definitely stomach. It's above my bellybutton, so not uterus. At first I thought maybe gas and bloating since I keep seeming to eat too much for dinner, but the fact it corresponded with when I went to bed last night suggests otherwise. It's a pain, not like I'm going to throw up, just like before diahorrea, but I don't have diahorrea. I am a bit constipated though. Could that be the cause? Or is this just my weird version of nausea/morning sickness?
