Last Friday I had sex and the condom broke. Never in my life have I experienced "condom bust". My ex and I have had sex a MILLION TIMES I met him when I was 15 and now I'm 25 this never happen to us before. I'm very very very nervous/scared. Earlier this week the smell of yogurt made me nausea. Today I was nausea and VERY SLEEPY. I work from home and slept majority of the day. My cycle is dated for Saturday. Is it to early for me to have symptoms?
