On brith control with possible pregnancy????????

1st off you guys need to know I am on the birth control pill yaz for 7 months now. I might have taken 1 too late, and took 1 right after I took perscription pain pills then had sex that night, the night I ovulated.
My last period was October 5.
I had sex during the time I was fertile possible on the day I ovulated which was anywhere from the 14-18th. On the 19th (according to calculations that would have been when I would have concieved) of October I got 2 pink spots on the tp. It was gone. Then on the 26th got 2 brown spots then it was gone. This whole time having slight cramping, tried, feeling like I was going to throw up and sometimes actually, boobs hurting.

Then on the 31st of October the day before I expected my period, I had brown discharge. It was not not normal period bleeding. It would only appear on the tp when i would wipe, not requiring a pantyliner or anything. That continued to the 1st of November. Last night (November 1st) had protected sex with a condom, but it was very dry inside but had sex anyway.

Today November 2nd, I woke up to redish spotting, but only when I wiped. I had to go out so I put a pantiliner on and went out. I came back an hour and 1/2 later checked and there was a little little section of this redish spotting. So, put a new one on at laid down for a nap. Woke up went to check and some blood came out of me in a string like fashion. But, went to wipe and there was only a little red spotting on the tp. Ever since, there is only a little spotting. I mean, It could be just an abonormal period.. but just wanted to make sure. I have not tested yet, was going to this week. But, does this sound like just a period *not pregnant* or, pregnancy bleeding *pregnant*, or a miscarriage?

I am feeling nauseated, boobs still hurt/itch a little cramping on and off.

My doc is not in the office today, so was just wondering what you thought.

Thanks so much!!
