My husband and I just started trying this month. I've been taking opks for a few months to predict my ovulation. If you see my picture you'll notice my peak day was CD15. I'm using clearblue advanced. This month we were so busy and my husband threw his back out and had to take a pain killer, so we did not BD 13-14. We tried on 15 but it didn't workout...he couldn't ejaculate. On 16 we BDed and didn't again. What do you think my chances are having BD the day peak? Please help!!
