So I had sex 2 days ago, I was at doctors this morning for something completely unrelated but they asked to do a pregnancy test, HOWEVER that test came back POSITIVE to my surprise.. I then went home did a further 3 more tests that all came back negative (they were different brand tests too). I'm so confused how they got a positive and I only get negatives. Anyone had this happen??? I know it's not possible to be pregnant after 2 days.... I don't get periods either since I came of birth control 5months ago and waiting on them to return
