Hi I had unprotected sex 4 weeks and 3 days ago and around a week after unprotected sex I came on early for a couple of days and had mild cramping in my lower right adomin should I still be worried about being pregnant? Cause I ve read about implantation bleeding? Also lastnight I experianced lower right adominal pain again and I ve got a few pregnancy symptons my breasts feel tender and I ve been so hungry and tierd is it too early to take a home pregnancy test and get a acurate result or shall I wait till my next period?
