I asked about bleeding this morning, ended up going to the maternity hospital. They did an ultrasound and said it was good, but my blood pressure was 140/90 when I arrived, they examined me, said the cervix is almost ready and put in a Foley catheter. My blood pressure hasn't dropped since 11 am, when I get up from the catheter, there's bleeding, my stomach hurts, sometimes contractions happen, my lower back hurts, I can't take it anymore... and my head is splitting. I ask them for a pain-relieving injection, they say there are no indications, I'm really scared of all this.
