I never actually knew if I was pregnant; I just had a feeling. I woke up feeling sick numerous times, had lower back pain, and was just extremely, unnecessarily emotional. However, yesterday, I started to spot. The blood was light pink. This morning, I woke up and went to the bathroom, and there was a strange looking clump on the toilet paper. It really looked like tissue. I have no cramps, and am not currently bleeding, but I have a yeast infection from the antibiotic my doctor prescribed for a UTI I never actually had (I was urinating constantly). What's going on?
