I stopped taking the pill about 3 weeks now, After only a couple of dayz stopping I got my period and now I should be getting it again in a week but I had sex and a couple hours later I was spotting lite pinkish red and than brown ? This is happening for two dayz now?

Spotting after sex can be normal. During sex, sometimes the cervix gets bumped and some blood gets into the vagina. Later, you may notice some spotting. This seems like the most likely cause, since you noted that the blood starts off pink and later is brown (new blood is bright red, then turns pink as it gets older, and old blood is brown).

Also, do not be suprised if your periods are not regular now that you are off the pill. You may have later periods than you expect and you may skip a period. It takes a while for your body to get used to not being on the pill.
