Period is due beginning of next week. For the past couple days my nipples have been a little sore and I have been having on and off period like cramping. Wednesday night I got a speck of blood in some cm (first photo) and Thursday night I had a little more (second photo) but it was only when I wiped once. I’m not spotting/ bleeding at all today. Could this be implantation? I already ovulated around the 4th- 5th, I was on letrozole and the blood test confirmed that. I’m waiting to test when I miss my period because I have been trying a year and have been unsuccessful so I don’t want to get my hopes up seeing a negative because of testing too early.
