could a doctor telling me I had Pelvic inflammatory disease really meant I was pregnant because I am & no PID? I didn't have sex for over a year & kept myself from wanting to be w/ men but had drinks on the weekend at the bar, unfortunately I ended up having a one night stand with someone who ejaculated in me 4 times in one night.  I had woke up later that day having lower back pain near my kidney area, it was no regular pain.  He used me obviously & I was blue about it all. He was just a typical guy, needless to say I was in pain for more than a week, I was with another man because I was acting out because he hurt me, when i was with this guy it hurt when he tried to have normal sex with me, because the top of my cervix hurt, which I knew why because the first guy HURT me by pentrating me deeply, this man ejaculated in me when I told HIM NOT TO & I freaked out & left him & went to hospital I told doctor about all the pain i felt in my lower back, how it hurt & he did a exam,  he later told me I didn't have a urinary tract infection , or was pregnant but had PID, but I am PREGNANT..1st one?

Summarized question: Do pelvic inflammatory disease and pregnancy have similar symptoms?
