Light Spotting?

Margaret • Living life with my fiancé & our two minis. 💕
I'm currently 10 weeks & 2 days, and last night after having sex, my fiancé noticed a small amount of blood. I brushed it off, because we had been a little rough during intercourse and I know that everything is rather tender and sensitive down there, so it was probably because of the sex.
But today it's continued, just a few pink drops here and there. No cramps, no other abnormal symptoms. 
I've read that light spotting can be a regular thing for pregnant women, but how many of you have experienced it?
I haven't talked to my doctor yet, but plan to very soon if it continues.
