So I've had sort of pressure in my lower abdomen the past several days as well as lower back pain. I'm VERY newly pregnant (just under 5 weeks) and have never been pregnant before, so I thought early symptoms? Nope, today I had trouble peeing and had my a-ha moment, which was, I have a UTI. Went to the doctor, he gave me Keflex though we won't know for sure if I have the UTI till next week.

I'm weary of taking Keflex when we don't know for sure if its a UTI. Anyone take Keflex or have a UTI super early?
