Help!

I cannot get pregnant this month since I had an early miscarriage and the doctor said we should wait 1 full cycle. I've been tracking my ovulation to make sure I get back to normal and I got my positive today for ovulation. My husband and I had sex today and the condom fell out right after finishing. We don't think any semen got in me just in the condom but I'm very nervous! Anyone else have this? Share your stories please!!
