In the past year, I have ovulated on day 14 twice, an the rest of the time always on day 15. Last month I started progesterone 200mg capsule vaginally after I confirmed O. After a BFN, I stopped and AF don't come for 4 days later. This month FF says I ovulated CD10. I have had a crazy schedule so haven't temped at the same time every day. I haven't used OPKs because I O so regularly and they stress me out. Can progesterone affect O for the following cycle?
