Today is 35 in my cycle and I'm 7 days late on my period. I have gotten period symptoms but no period. I took three test but all negative. I'm not sure if all these symptoms are just all in my head cause I think I may be pregnant or if I should test. There's not even a little spotting, but I feel like I'm constantly wet down there and have a lot of white milky discharge. I know there is a possibility because my boyfriend cums in me. Should I just go get a blood test?
