What's the matter with me?

I'm just looking for ideas, as I can't get a doctor's appointment. For the last 2-3 weeks I've had an upset stomach, a mild headache with feeling a bit fuzzy, and sometimes felt shattered. Initially I thought it was because I wasn't eating enough with BF Blythe, but I've not eaten enough a couple of other times in the last 6 months and not felt like this, plus the upset stomach doesn't feel like hunger. I actually feel like I'm pregnant, but it's been 6 weeks since I last had unprotected sex and I tested last week and got a BFN, so I know it's not that.
