Pregnant Possibly 🤔?

So my last period was Feb 9th-12th immediately on the 13 I had sex then it was every other day after that so the days were the 13th, 15th, 17th, 19th, and 21st. The 21st was the day I ovulated we continued at every other day but I noticed that the 4th and 6th day after ovulation I spotted where it was noticable when I wiped. On the 4th day after ovulation it was a red dot them on the 6th day it was pinkish since the days I noticed I spotted I've been cramping only in the abdomen area where my uterus is and my boobs feel heavy full and painful when I sit up after laying down relaxing in my back for a while has anyone else experienced this or have an idea of what could possibly be going on because I've been TTC for almost 10yrs now I have tubal blockage and fibroids and I've never experienced this at all

Thanks in advance
