Hey girls?

Hey girls ? Today at 2 am I went to the bathroom, I see that there's a little blockage with bloody streaks on the paper. And it's been happening several times already. A bit by bit and with blood mixed in. And my stomach is also being cleaned out. How long did you all have this after giving birth? Because I'm already 40 weeks pregnant. And the blockage with blood always goes away in the hospital after the puncture of the bladder, during the water discharge. So I'm wondering what to expect? When will it start? ??
