I was on my period and 3 days later my boyfriend and I had sex. We didn't use a condom but we didn't finish. To be on the safe side I went to plan parenthood and they gave my Next Choice. About 2-3 days after that I got what I believe to be my period again. I was bleeding for about 5 days like I would normally on my period (it was a big heavier though). Now, its about a week past the time I would normally get my period. I'm not sure when I should be expecting it. And I'm not sure if this would be related at all but I've been having the urge to pee a lot. But, it seems like I have the symptoms for a UTI. I've been trying not to stress out about this because I know that can cause my period to be late. Also, I live with two other women, My mother is going through menopause and that seems to have been causing my sister and I to have irregular periods for the past few months. Any advice would be great.
