I need help

I'm currently 11 weeks I've have a miscarriage prior to this pregnancy and I'm so worried about every little thing! I'd really love to get a at home fetal dopper but with everything going on I dont have the extra money as of right now I'm saving up for a vehicle so I can get back and forth to all the doctors appointments with this pregnancy my blood pressure has been really high I'm just so worried I was just wondering if anyone on this app have an extra fetal dopper a used one I really dont care what condition it's in but if not I totally understand and I'm sorry that I'm asking I've never been in this position to ask for things and it just makes me upset bc I dont want any harsh comments for asking
