I've been on birth control (ortho tri cyclen) for about a year and a half now. Since I started it my boyfriend of five years and I stopped using condoms (there's no need to worry about STDs, we've only really been with each other). However, he still never finished inside of me because it still worries me. I haven't missed a period or anything but I'm not great at taking my pill at exactly the same time. I usually do but maybe once a week I'll take it a few hours late. Because of this I'm sort of worried about pregnancy. My pill makes me more anxious than normal so I worry about everything. Even though I haven't missed a period I have still been worrying about pregnancy lately. What are my chances of pregnancy with my usage of the pill? Someone calm my nerves!!!
