Pregnancy Info HOME

Just looking for some insight & reassurance & hope! I have a 33/34 day cycle, and it's fairly regular. By following fertility apps on my phone, I've always had a general idea of when my fertile window is (days 14/15-19/20), & this was confirmed twice with positive OPKs (day 18) on 2 different cycles. This last cycle, I noticed EWCM on day 12. I did not have a postive OPK until day 14, which I'm assuming would mean I ovulated day 16. This is distressing as my husband works out of town & I had planned to be with him on days 17-19, thinking that was my ideal time. So - based on the EWCM & the positive OPK on day 14, is there any chance at all that I could've conceived this cycle, being together only on days 17-19? Is there any chance I could've had an early surge? Or are the OPKs usually accurate & you ovuluate approx 36hrs after a happy face? (FYI: I had a happy face day 14, & nothing day 15). I think I know the answer but I'm looking for some hope!! Thanks
