I took Nest Choice The next day after having sex. I took it at 9:40 in the morning. Later on that day I started bleeding when I went to pee. It was very painful. I was thinking I came down with a UTI. I took the other pill 12 hours later like it said and then the blood slowed down and then evientually stopped. I'm not bleeding anymore and I don't experience any pain while urinating. Was that just a side effect of the pill or is something more serious going on?
