Period is 2 days late officially and I know when I ovulated for sure because I took letrozole and was monitored by my doctor but my breast started to get sore on the sides yesterday this normally happens 2 weeks before af but didn’t start hurting until yesterday at 1 day late I hope I still get a bfp I will test Monday at 4 days late if I don’t get it! Fingers crossed has this happened to anyone on letrozole? That has had confirmed ovulation ?
