Hey all, after giving up hoplessly, I think I might be preggers. Is it possible to have pos before your AF is even due? I ov on the 18th of this month and BD. The following week had red spotting so, out of curiousity tested. It was faint pos. My AF is not due until this sun and i've done 5 tests...4/5 are faint pos. Can something go wrong between now and then?
