Miscarriage after pap smear?

In the last 2 weeks I had to go to urgent care and the emergency room due to the intense bleeding and pain I was in. Two days after having a pap smear, I started (what I thought was) my period. However, I wasn't expecting my period for another 2 weeks and this was unlike ANYTHING I've experienced in the 12 years I've been menstruating.

I didn't have a urine test until a week after the pain started and it wasn't for another week after that where I had a blood test for pregnancy, so right now there's no way of knowing if I was actually pregnant (the doctor in the ER refused to give me an ultrasound). I know my body and I know when something is severely wrong with it. Plus I was having unprotected sex a month before all this happened. I strongly believe I either had a miscarriage or have endometriosis. I'm going to see my doctor soon to rule out endometriosis or possible cyst. If the ultrasound comes back clear, then I really truly believe it was a miscarriage.

What I'm asking, though, is if the pap smear could've initiated any of this? I've been reading other forums and this has happened to MANY other women. Within 24-36 hours, they've also miscarried. I'm sure it's not a significant enough amount to cause alarm, but I'm just wondering if anyone's spoken to a doctor about this or had a similar case?
