for the past few months me and my boyfriend have been having unprotected sex, only becuase he is allergic to laxtex, he hasnt started to cum in me untill about a month ago, and we have been trying to get me pregnant we have had sex every night so far now i havent gotten my period yet, i usually dont get it till the end of the month but the week before i get cramps and signs telling me soon ill be on my period but i havent been getting them yet, i dont know if there is a chance i could be pregnant but if i dont get my period when would be the best chance to take a test to see if iam pregnant? and should i just go to the doctors for that or take a home pregnancy test?
