1 night ago I was having sex and the condom broke, I went home that day and took the morning after pill and then the next morning I had unprotected sex, but he pulled out. I've been on birth control for a year but had some complications getting this next pack so I was off it for about 4 days and as of this morning I've taken it for three days. Do I need another morning after pill? I'm really scared this will mess up my system...
