Hi welcome to H.C.M.Forum. you are over anxious about pregnancy
. any how it is 33rd day you get your urine tested for pregnancy test, immediatly you will come to know whether you are pregnant. if negative also don't get discouraged. for fertility
testing if only females are tested it is not sufficient. both the partners should be tested. have sex from 10th day to 20th day. don't have on other days. don't get up immediately after sex. best of luck.
