I woke up this morning w/ stomach pain but I knew it was to use the bathroom... well I was sweating really bad and my stomach had an excruciating pain, but it would come and go. I think it’s like irritable bowel syndrome.... well when I finally was able to use it, it was (tmi) diarrhea.... but my stomach still has a pain as well as my lower back. I haven’t been bleeding or anything. So maybe it’s a stomach bug? I’ll be 17 weeks this week. I don’t really have an appetite
