I don’t know what’s going on

Khadijah

So I’ve been have lower cramps, back pain, nausea and been extremely exhausted for 2 weeks now. Also I’ve been having issues lately when trying to eat. I would get food and take a bite and literally hate it. I can only eat certain things. My period came early this month and was real light and very short. After coming off I had pink discharge two days later. I took a pregnancy test and it was negative. Went to the hospital today they see nothing wrong and send me home with nausea pills. Has anybody else experienced this and can tell me what’s going on. I’m trying to get a primary doctors visit but I go out of town this week and don’t know if it’s gonna be possible. My ex and best friend say it looks like I’m putting on weight and I’ve actually been working out lately.😢😢
