Birth control ?

My body is very sensitive to things. The plan b which I’ve taken twice had an insane effect on my body. The first time I took it I gained 30 pounds in two months, the second time I broke out all over my body.

After hearing what my friends have experienced and the issue of infertility, I am scared to get on birth control.

My bf wants me to get on it because condoms irritate my vag and we aren’t ready for kids.

Suggestions? Advice?
