Throbbing pulsing feeling in calf of leg first week on the pill

lilly

I’m having a throbbing pulsing feeling in the side of calf in my leg since I’ve gotten into bed it’s not painful but a really strange feeling in leg I feel like my leg has a heartbeat I can see my leg actually pulsing in and out I’m just wondering is this normal I haven’t done any physical activity like exercise. I’m worried as I’m now on my first week on the pill and I know a side effect on the pill is blood clot I’m just wondering should I be worried ?
