Hello doctor. My boyfriend is sexually active, but the problem is that he does not want to use condoms at all! I tried thousand times to explain to him but he does not want it. Instead, I told him that I would take proper contraception timely so that I do not get pregnant. We agreed on sex at most once a month or once in two months. I am 19 years old, please suggest what precautions should I take? What pills are recommended? Will taking too much contraception at this age prove harmful for future? Will I be able to conceive later? Will I be too prone to STIs? If so, then how often should I get my checkups? Will I have I take frequent blood tests and ultrasounds? What can I do for precautions against stis? I need serious advice! Please help me, what should I do?
