TMI: Sex and spotting?

I woke up this morning and used the washroom and noticed a little hint of blood as I got up from the toilet. So I sat back down and wiped again and noticed it on the toilet paper. Is this normal? I plan on calling my doctor as soon as the office opens in like an hour. This never happened to me during my first pregnancy and we literally had sex everyday until my pregnancy was over. Last night, we had rough(ish) sex. The first round I felt the orgasm there but I just couldn't climax all the way. We then took a break for awhile after then started up with round two. After awhile I got on top and that's when it finally happened and for some odd reason, I actually cried as I got mine (couldn't control it). Is that even normal? I also felt a bit swollen but was satisfied and didn't see any blood then when I used the washroom before bed. So now I don't really know what to think. This is new to me. I'm 9 weeks + 1 day.
