Hi Doctors. Im really begging for your help. I had my last period last jan 26 and my husband and I had unprotected sex last feb 9(12am) and feb 10 (2am). I took the ECP (4 pills of nordette) jan 11 at around 2pm. The second dosage, I wasn't able to take it on time. Instead of drinking it at exactly 12hrs later, was able to drink it after 17hrs. So I decided to drink another dosage again just to make sure... I took the 3rd dosage at exactly 12 hours later after I took the second dosage. All in all I took 12 tabs instead of 8. Didn't experience any spotting just headaches and breast tenderness. Its already march 2 and I still don't have my period. Is there a chance that I'm pregnant?:( or it just messed up my cycle? Please response. Thank you.
