alright, here’s the deal. my boyfriend and i had unprotected sex on june second. that would be a month and day from that point today.  he did NOT ejaculate in me, but i know there’s such thing as pre-***. then we had procter sex on june seventh. my period was due the 12th that month and bleeding on the 10th. i am sometimes irregular by a few days, the bleeding lasted up to six days and was heavy the first two days. then slowly grew less heavy throughout the days as normal but on the last day there was brown blood and red blood mixed. i am worried that it could of been implantation bleeding. i waited until three weeks after i had unprotected sex to take a pregnancy test. that would of been on the 23rd of june. it was negative. then i took one the next thursday which would of been three weeks for june seventh. also negative. then i took another one a couple of days ago. negative. should i be worried? is there a possibility i could be pregnant? or am i just scaring myself, i have symptoms but i also know such symptoms can be related to other things such as pms or illnesses. please respond!! thank you

3 Pregnancy test = negative? Thats too much. Then that means you're not pregnant.
