I am 16 years old... I had my period a couple of months ago but I had it twice in one month but people said that's normal sometimes because of weather change...
I had sex with my boyfriend we used a condom but I was drunk.. and can't remember much .I thought I missed my period but then it started 3 days ago.. the 1st day was reaaaally heavy second day was very light.. now on the third day I don't even need a pad... whats going on am I pregnant I'm really worried

As you know a condom is far from 100 percent effective, most rate it at a 3 to 10 percent failure rate. If he did use one, if you were too drunk who really knows. Men often say they did, even if they did not, since that is what they think the girl wants to hear.

But a very light period is a sign, but it can be a dozen other things also.

Best to wait till the next normal time for your period, and then if it misses, do a pregnancy test, Use the urine first thing in the morning when you wake up
