I was on BC (injection) for two years before stopping about a year ago. Boyfriend and I used condoms until a week ago. My concern is about my periods. AF has not been "normal" since coming off the injection. AF before was never regular but they did come every month. Since coming off the injection, sometimes I will go for 3 months without, sometimes 1 and the longest was 5 months. Is this going to make it impossible for us to conceive?
