I would be very grateful for some help because I am pretty confused! TTC #1. DH and I don't DTD that much so trying to be focussed on the fertile window. Average 27 day cycle. Two apps giving me completely different fertile windows! Confused.com. Don't want to try OPKs just yet as trying to stay relaxed about TTC. Which days of my cycle would typically be my fertile ones? Currently on day 11. Thank you!
