Hey ladies i need your advise. Here is my story... I have a daughter, she ' 4 years . on May 16 I found out I was pregnant (a big surprised, by the way, cuz I was on birth control ( no taking every day) but the same day that I found out about my baby, I got an emergency surgery cuz it was an ectopic pregnancy . Well after that happened I decided to start using the Patch as a BC , the first day that I started the patch, me & my husband had sex . My last period was on June 13 , on the 22nd of this month I took a pregnancy test, Negative but I haven't get my period yet.. I don't know if I should take a 2nd test or what?????? Please help!
