I normally keep very close tabs on when my period starts and ends, but recently had my cell phone stolen. That is where I was keeping track. I've backtracked to figure out about where I should be now, so I may be a day or two off in my calculations.
My fiance and I were engaging in some pretty heavy petting and dry humping, and were only separated by our underwear. We've done this before, but never escalated to actual sex until four days ago. I was already about 9 days late when we first had sex, but I had thought my period was coming because of some cramping and changes to my vagina.
Now I'm suffering from mild to severe abdominal cramping, not unlike my usual pms symptoms, and still have no spotting or discharge of any kind.
