I recently got off of the IUD (skyla) in mid May. I had my first normal period starting on June 9th. I have always been very regular at 28 day cycle. I had unprotected sex on June 20th. I was estimated to be ovulating  on the 23th and had egg white cm from June 19-23. Since about a week ago, I had been having some of the worst breast tenderness and pain of my life. I can't sleep on them and even barely grazing them on something hurts. Yesterday, I also noticed some minor cramps with some bright pink cm, which continued into today. On top of all of this, I am exhausted and took a 4 hour nap today. Could I be pregnant? And if so, when should I test with frer hpt to know for sure? My estimated Af is suppose to begin on the 8-9th of July. Thanks for any advice!
