Cramping a day after Pfizer vaccine

Hello, yesterday I received my first dose of Pfizer. I was 12w3d. I got a sore arm a few hours later and then a headache from the evening and I still have it. I started cramping about 30 mins ago, mostly on my left side. I haven’t had any cramping during this pregnancy until now so I’m a little worried and my dr isn’t in until Tuesday to ask. Did anyone have similar symptoms after and baby was ok? Thank you 😊
