Pains when pregnant?! Please read

Erin

Hi, I’m just under 12 weeks pregnant and have been experiencing some really bad pains in my stomach, I’ve been crying so much because I’m scared that something is wrong but I can hear the baby’s heartbeat on the Doppler I have but these pains are really bad, I go to have my scan on Wednesday and am really scared they’re gonna say I’ve lost the baby or that something is wrong with it, has anyone else been experiencing this?? Or similar, it’s really panicking me 😭
