So... On June 21st AF came to town for about 5 days which is normal... Well... July come around and I was eating a salad from McDonald's, and about 2 hours after eating it.. I started to feel really sick (Note I am already 2 days late for AF) Well I left work went home and ended up getting sick that night. Next day (July 24th) I had a headache that I cant even begin to describe in words. No matter what I did my head was pounding and I was still feeling nauseous.. I went to the hospital, where they did blood work and a urine test  and everything come back fine and they said that I had a UTI and that is what cause me to get sick.  well.. I personally think it was food poison. Just my option. They gave me some meds which I never got filled. Well here I am 3 weeks and 2 days later and I am having no signs of AF coming to town. I have taken a number of HPT for them to all come back negative... Can I have some advise of what my chances of being pregnant is? For the past 2 weeks, after work.. All I wanna do is go home and go to bed.. I don't like the smell of certain things anymore.. and alot of times after I  eat I feel like I am going to get sick. When I bend over a bunch, I feel like I am about to get sick, and I climb a flight of stairs every morning and by the time I make it to the top Im dizzy... This just started happening as well... Any thoughts?
