My boyfriend and I have recently started trying to have sex, but we haven't been that successful. We only have intercourse for about a minute becasue it is'nt that comfortable for me, I develop a burning sensation. Any ideas what that's from? or how to prevent it? (my boyfriend wears a condom and does not come close to ever ejaculating).

I take all my pills regularly, and we use condoms when we try. Currently I was suppose to get my period on a Monday, and it is now Friday and I still have my last brown pill left to take. Is there anything to worry about? Why hasn't my period come yet? Do you think I might be pregnant?
