Always worried…

Im officially 13 weeks so almost out of the 1st trimester. I hate having to wait so long for my doctor to do another scan. I’m always worried that my baby isn’t growing or something is wrong. I feel fine though but still worry. I wish I could do scans everyday so maybe I’d worry less. I do have my own Doppler but I only catch glimpses of the HB for maybe a few seconds before I lose it again. I know every pregnancy is different but I’m jealous that a friend of mine who is only 2 days ahead of me is able to feel her baby move. I know it’ll happen before I know it just ready to feel him move and have some reassurance…
