Second guessing the Doc.

So things are different because of COVID-19 Which I understand that but I feel like my doctor isn’t taking the right steps for my care. She Prescribing me an injection type blood thinner without having me get labs first. The placenta uses Coagulated blood so my blood being super thin can’t be totally safe for my baby. Plus I’m already a heavenly bleeder which Is common for most red heads. I’m worried my blood my be to thin when it come time to deliver my baby and since I’m planning an at home birth I worry about bleeding out. My doctor seems to busy to hear my concerns. And says labs can wait.
