I had my last period may 8-12. I then had unprotected sex on may 15th and 17th. My period tracker said I will not ovulate until may 21 (14 days into my cycle) but I noticed clear mucus on may 18th (a day after I had unprotected sex) I totally freaked out and went to go get plan b. I took it exactly 36 hrs after having unprotected sex. As of now i am cramping and have been for the past week on and off..Could I be pregnant? Will plan b work for me? Was I already ovulating or does the clear mucus let's me know i am about to ovulate? I'm so stressed I am making myself physically sick!
