my period was stared on 22 August and I had unprotected sex on 28 August even though he pulled out i took p2 on 30th August , on 4th September I experienced heavy bleeding as if I'm on my period and it lasted for three days last week I had stretchy clear discharge similar to the one I use to have when I ovulate today being 19th September I expected my period, even though I'm having the usual pms which includes tender nipples like I used to get but I didn't get my period, I did urine test yesterday being 18 and it was negative, I use to have 28, 29 days cycle......
