Uy, I understand your worry talaga, lalo na at malapit mo nang i-deliver! But honestly, this is something you really need to discuss with your OB as soon as possible, don't wait lang for the message, maybe call the clinic directly kaya they can see you sooner, especially at 37 weeks ka na.
A few of my mum friends went through something similar during pregnancy, at ang important talaga ay makuha agad ang proper guidance from your doctor, they'll know exactly what's safe for you and baby at this stage. Sending you peace of mind, mama! Your OB will take good care of you both.
