Hi everyone my name is elizabeth and I am 21 yrs old. The reason for my message its because I think I am pregnant. My period has always been regular every month i'll get my period but this month its different. July 15th was when I received my last period so I was expecting my period around the 15th of august. I had unprotected sex with my boyfriend on august 14th. And as of today I haven't received my period. My boyfriend assures me that he didn't come inside of me but I still have the doubt. I have taken three pregnancy tests and all three have came out negative. Is it too early to take pregnancy test?? It's being two weeks since my sexual experience. And are blood test better than urine test??

Thank you everyone for your comments
