Hi! I need to know more on the ECP. I had sex last jan 16 and we are unprotected..so I did took nordette pill as per instruction..still no signs of withdrawal bleeding. So again we had it last Jan 28..still unprotected. My due suppose to be this coming Feb 4. I am still waiting for my period. Is it normal effect of the ECP? I had PT last Monday but its negative. For now I do not want to get pregnat not ready for this. But my partner want to, I did not told him I took ECP. This is my first time to use this ECP, sometime I feel lil pain in my breast but still no signs that I will have my monthly peiod. As far a I know after 5 days I should experience withdrawal bleeding but its not happening. Kind the worried. Please advise. Thank you.
