Pregnant or period

My husband works out of town but I know that on october 26th we had unprotected sex. On november 2nd I had some blood streaked CM. Yesterday i had a very pink spotting and almost super watery. Today I am having a bit of brown spotting and its a bit thicker. Is this a good chance we could be pregnant? Or is this just my period starting? My cervix is super high/tilted, firm and closed.
