Do Human Chorionic Gonadotropin Or Human Papillomavirus Cause Bleeding

I am 49 years old and for the last 4 years I have had my period about 3- 4 times a year. Since October of 2010, I have done 4 rouds of the HCG and following each round within a week, I have gotten a light period lasting about 3-5 days. I also noticed that I have light bleeding after intercourse. I recently had a pap and I have HPV. I am waiting to see a specialist but I"m wondering if the HCG could have caused some of the bleeding or is it more of because of the HPV?
