my boyfriend and i had protected sex, like 10 or more days after my period, then next month i still received my period on the normal time? should i be worried about being pregnant or not?

If you are having unprotected sex, yes you should be worried that you could become pregnant. Are you pregnant now? I don't know. Take a pregnancy test using first morning urine.

It's simple. Do you want kids now? If so, continue on this path. No? Then get on birth control and use a back up contraceptive method.

probably not. no bc is 100% effective, so there's always some chance of getting pregnant. but as long as you continue to use protection consistently and correctly you shouldn't worry too much unless you miss a period.
how old are you? are you really ready to be having sex?

was it protected or unprotected sex? i thought it said protected.

I read unprotected, my bad...now I'm confused.
