Is it normal?

I found the babys heartbeat at the bottom of my right side at cervix or above the vagina? Babys heartbeat is strong and good its like its always chilling down there lol this is my second pregnancy. With my daughter (1st pregnancy) i found her heartbeat up high near my belly button? This ones down low. Idk i just get worried lol 😩 im 15 weeks 2 days
