I think I might be pregnant, but it's too early to detect with a over-the-counter test. I'm 5'2, and 103lbs and 25 years old. my body hasn't changed since I was like 15, and randomly, I cannot get my pants over my hips, I'm developing a small pouch in my lower abdomen, I'm VERY tired, VERY irritable, and notice nausea after eating. I'm concerned because I'm on anti-depressants and adderall for my add and I know these are dangerous during pregnancy, but if I'm not in fact pregnant, I shouldn't stop either medicine- what do I do?
