Hollie
So, me and my SO we having sex and we had never used a condum before so we tried it. Well it ripped right at the end and he did finish. So I took plan be like 2 hours later but I'm a twin and I may have been ovulating don't know so I'm worried about being able to have multiple eggs. I'm not on birth control yet I had to cancel my appointment before this happened. So, has anyone had them happen and if so did plan b help or did it not work?
