Well i want to start off by explaining my case i had recently got my period on April13 and it ended on april 18 rite after i had unprotected sex on a regularly basis in other words each day and well i was kinda worried so on the 22 of april i went to the clinic and my doctor told me it was to early i took the pregnancy test even though and came out negative so my doctor made a follow up appointment for may 17th and told me to wait a little longer because you can only be really shure if your pregnant after youve missed your periood thats how i get to my main question....okaii so yesturday may 13 i was supose to get my period and i didnt im really stessed out i know i should just relax because i might be late for the same reason because im stressing so i hope someone can reaally give my some advice it would be really helpful thanks
