Another update.
The Neurofen worked to reduce the flow significantly, and the blood changed from red to brown, which was reassuring. So I didn't have to have a D&C Friday. THANK GOD. Instead, I took my daughter to the pool! This was great for 30 minutes and then she vomited everywhere. I may never show my face there again. Still better than the D&C though.
However.
I am still (!) bleeding. It comes and goes, but never goes entirely; I got away without a pad for a bit, but at the cost of stained undies. I feel like I'm keeping the pad manufacturers in business. Ringing the OB again today to let her know and find out what we do from here.
My best friend is hugely pregnant. I am hoping with every fibre of my being that I don't end up having a D&C while she has her baby. Murphy's Law can sod off.
