I had a miscarriage in March so we know we can achieve conception. But, saying that, it hasn't happened again since. I am a bit confused...when we get a positive ov test, when is the best time to BD? I know obviously straight away, but for how many days after? We are also BD the days before - is this too much? It is sooooo frustrating to know it can happen! We did it before using my monthly cycles website (which we are also using). Our bedroom is like a science laboratory!!!! Only kidding!!!
