Freaking out

Im 9 weeks 5 days mc 4 months ago at just over 7 weeks and today i woke up and completly convinced myself im going to misscary just because when i was laying down my partner said my boobs felt smaller. So i told myself im not pregnant anymore and scrolled the internet to try and find a baby doppler that i could bye today with no luck. I get up and then he tells me on no your boobs are still big guess its just cause you were laying down. Anyone else having freak outs like this?
