I had unprotected sex on 18thmay, i was highly fertile, on a range of 1 to 10 i was 10 as per my ovulation chart. Now its been a week since sex and i have left pelvic pain and sore nipples and breasts. Really tender. My discharge has gone from egg white to sticky, glue like. I have thyroid. My last period was right on time on 4th May, next period is due on 1st June. What is this happening? When should i check? Please help!?
