Starting to get worried.

Im 8 weeks today n I've been reading a lot of different stuff about heartrate n fetal development stopping at 8 weeks n I'm not able to see a doctor unless I go to the emergency room which then they won't give me an ultrasound n I'd have to pay for it out of pocket, using the home doppler the heartrate at the most reached 130. My sister said she saw it reach 150 n the baby was moving around but I'm worried that my bean isnt growing or isnt healthy. Anyone else?
