I am a 24 year old girl and have a history of endometrosis. I was taken off of my birth control about 6 weeks ago due to adverse reactions with it. I have a Latex allergy and me and my husband choose not to use condoms. My ob/gyn does not seem concerned with me not being on birth control. What are the chances that I can get pregnant? I am also on an anti-depressant and am worried that I will not find out if I get pregnant until it is to late to stop my medication before it could possibly do some harm to my baby.
