My boyfriend and I had unprotected sex on the 3rd day of my period. It's schedule is from Dec 21-25. I took plan B on the 26th just in case. We had unprotected sex again on the 27the and 29th. My ovulation schedule is from Dec 28- Jan 3. I started spotting light pink then brown discharge on the 31st and started getting mild cramping and very tender breasts and nipples.
What could be happening?? Am I pregnant?? Is what Im experiencing implantation????
