Hey Flopsy, midwife here. I am so sorry about what you're going through. Accepting uncertainty is one of the hardest things
Can you call the hospital's maternity ward? I had a call like that, from a young mum who was bleeding at 15 weeks and too anxious to wait for the scan, and I offered her to come to the ward and listen to her baby with the doppler. Obviously warning her that it had the potential to make her more distressed if the baby's heart was not found, but if that had happened, we have a portable USS machine in the ward and I would have called the registrar to do a bedside scan.
We could hear her baby loud and clear, and that gave her energy and strength to wait until her scan.
5 months ago I went to a house to pick up something I had ordered in marketplace. The woman who opened the door broke into a massive smile when she saw me. I knew I knew her from somewhere but couldn't quite pick it up. She asked me to wait and went to pick up a gorgeous, chubby baby and put her in my arms. "You were right, she was ok!". I got something in my eye on the way back home.
Although it is impossible to know without a scan, I am hoping that the blood may be coming from a small early retroplacental bleed, which is an accummulation of blood that sometimes happens when the placenta implants. When this happens early in pregnancy, often women keep bleeding until the pocket of blood empties naturally (not to mistake for the retroplacental haemorrhage that sometimes happens closer to term when there is a placental abruption, so if you google it take this into consideration). If this is what it is, then often the little bag of blood empties and the pregnancy continues as normal.
Right now your uterus is the strongest protection for your baby. There is nothing you can do proactively to protect her, which is incredibly frustrating, except to wish and hope she is ok. Please keep us posted. Big, big hugs!
