So the condom broke while my husband and I were in the middle of sex. He had not finished yet. We stopped and put another one on. I use birth control pills, but do not take them at the same time every day. It is usually in a two hour time frame. I am supposed to start my period on Monday. I am wondering if I should take Plan B, or just not worry. He did not ejujulate(sorry for the horrible spelling), but I do not trust the pill 100%.
