So me and my boyfriend have been together for 4 years this year in August, I’ve been on the pill, but couldn’t get into the habit of taking them everyday so I got the implant. Ever since I had that removed (which was 3 years ago), my periods have been all of the place, meaning can be 2 weeks late or a week early, if differs so much. But when we have sex, he doesn’t pull out, we’ve been doing this for 3 years and I’ve never gotten pregnant. Is this something to worry about or do you reckon just wrong timing?
