I'm 29 weeks and 3 days. I had light red bleeding after sex. I don't bleed any other time besides when we have sex but this time was a bit more. Baby is moving just fine and no cramping. Anyone else have this? I have a docs appt Tuesday and the last time I went to l&d; for it everything turned out to be fine and the nurse said it was normal
