I have Endometriosis and my GYN recommended me to stay on BC and not stop to have a period. I have done this for 2 years and came off my pills in December to get pregnant. I started having a few pregnancy symptoms and my period is late, but the HPT is negative. What should I do now? Do I wait for another week to take a pregnancy test or should I go have a blood test done? I am afraid that being on BC constantly may affect my chances of getting pregnant. Any advise.
