Soooo.... since the end of my last period my husband has came in me a total of 7 times(5 of those times were in the last 2 days) . My period is supposed to come next week. Is there a good chance I could be pregnant??

Side note: He smokes but not a lot

UPDATE: Soooo I was getting ready for work and all of the sudden I went to pee and I noticed there was light red colored blood in my underwear. My period is supposed to be here the end of next week is it possible my period has just come early because of all the sexual activity??
