Talk me off a cliff

We are avoiding pregnancy. I dont know where else to post. Im very scared. My anxiety is through the roof. I never ovulate this early. I havent been temping. I do however check my mucous and cervix. We had sex one day after my period ended. The mucous that day was sticky feeling and i figured i was in the clear, so we didnt use protection. Im super freaked out that this could turn into a pregnancy. Once its a positive ovulation test, doesnt that mean ovulation actually happens the next day? And what are my chances of being in the clear? Please talk me off a cliff.
