I'm 28 weeks pregnant and i'm bleeding can my baby survive if i bleed until my due date but this bleeding comes sometimes 2 or 3 times per week can this kind of bleeding cause a miscarriage or should i worry?

I would contact your OBGYN for guidance. This could be simple marginal bleeding from the placental attachment and if minimal you may carry to term. You are at higher risk of premature delivery & need to have a plan in place on when to go in for an evaluation. Bad things can happen to any pregnancy. This is worth close monitoring but not a predictor of automatic miscarriage.
