miscarriage or just because of sex??

My husband and I just had sex and when I whipped myself off I was bleeding. I mean we have had sex before and I bleed as well. I'm 6 weeks pregnant and my husband and I have had sex a few times and each time I bleed. Each time more than the last. I read it was because your increase in blood vessels in your vagina and in your cervix and also because your increase in blood. Am I ok?? Is everything ok??
