Light bleeding ? TTC

I’m 9 dpo. Last night my husband and I had sex, wasn’t rough or anything. I started bleeding. No cramps. I haven’t bled since. We are TTC and I thought my period was starting early. Do I still have a chance to be pregnant since I only bled then and nothing since? Or should I count myself out? My period is due Saturday. I haven’t had any cramps either. I had some light spotting for a day the other day but that didn’t last long either. Has anyone had this and ended up being pregnant?
