Hi, I Got My Period A Couple Of Days Early.

Hi,
I got my period a couple of days early. Normally I have really heavy bleeding the first two days and it's a very bright red color. I've had light bleeding and it's kind of pinkish in color sometimes mixed with red and sometimes brown. I had a chemical pregnancy just a month ago could this cause my period to be abnormal or could I possibly be pregnant. I've also had pregnancy symptoms that go along with it. And I've taken pregnancy test and to me it looks like a very faint positive but I'm not sure.

Thank you so much.
