please help, i am 16 and have been with my boyfriend for 6 months now, we have been talking about becoming sexually active, but both feel that me becoming pregnant is a big no no. we decided that a combination of a contraceptive pill and condoms is the safest root, the problem is i haven't had a period for 4 months, and before that i hadn't had a period for 6, i had a constant and regular period for year and a half before this though, which is what is confusing me. can i still get pregnant if i haven't got a period and what should i do? please help as i am worried about both my lack of period and contraception, any enlightenment would be greatly appreciated, thanks.
