We had begin trying in January. ..and nothing. ... we were in separate places 3 weeks...had sex I had a cycle...and 3 weeks later pregnant....maybe you have to take a break....when we 1st started trying we would have sex 20 days of a 30 day cycle...no exaggeration. ..and I think we just needed that detox period and BAM
Theres a trying to conceive forum you could search old posts on. I think there are so many factors. Can you tell when you're ovulating? For me it's really obvious but my friend didn't ovulate & had to seek an egg donor & do IVF--had nothing to do with her age. Good luck. 6 months isn't too long yet.
Just have fun and don't try to get pregnant and that's when it happens. I tried for over a year and when I gave up I was pregnant. I'm now 8 weeks. Good luck
