Could I be pregnant?

Frankie

My boyfriend and I had sex 3 times when I was ovulating and I'm now 2 days late which I've never been late before.. I've taken many hpt which have been negative and I went to the doctor today and the urine test was negative so they took blood! I don't have any symptoms of my AF coming but I spotted brown 2 days last week and I've been super dizzy and tired and my boobs have been a different type of soreness! Hoping this is the month!!
