so i kinda think i messed up last month with my birth control patch. i didnt pick up my perscription in time and i put it on a few days late. me and my husband did the deed and didnt use protection. we have 2 kids already and i think im pregnant. how soon can i test if my period is supposed to be here in 3days.ive had m patch on for the last 3 weeks and its time to take it off for my period. if i have the patch on then will that mess with the results? ive been nauseous and emotional i dont know if its all in my head or if i really could be pregnant. its just a feeling but with the past 2 pregnancies i knew i was pregnant before i took the test. intuition. i guess what im asking is when should i take the test and will the patch effect the results?
