This was my first cycle tracking BBT and I just got my first BFP this morning. I took a test on Tuesday (3/1) and had faint lines and then this morning took a FRER and it was obvious and then took a digital today and it says pregnant.

My question however is when the heck did I ovulate? I am trying to figure out how many DPO I am but I honestly thought I was out for this month as I never had the huge shift in temps and I never had a positive OPK. (I woke up with a awful cold on CD 18 so I am attributing that spike to illness)
