Finally pinpointed ovulation, now spotting sometimes when I wipe?????

So I was expected to ovulate on October 13th but I ended up ovulating on the 10th. My fiancé and I have been doing the BD everyday since the 7th. Ever since the 10th, every time we do the BD I end up having a few drops of blood after BD and then the following morning after. Then it goes away. It’s starting to increase slightly and it’s now scaring me a little. Any ideas or similar stories? Or should I go to the doctor ASAP?
