The feeling you get when your period start.

The thing is my sister is pregnant and she never wanted a 3rd she was not careful and ended up pregnant we have been trying for over a yr we did stop for a bit in Sep till Feb well kind of I never went back on bc. I don't know if I want to cry or scream. As the same thing happened with her 1st and my 2nd she just ended up pregnant and we had been trying for over a yr then as well and she just was not careful.
