Stomach cramps

I am currently around 6 weeks pregnant, and I’ve had stomach cramps on and off but mostly on for the past 3 days these pains just feel like period pains sometimes there mild sometimes there quite sore, I also have pain in the chest area. (No blood)

I went to the emergency Department yesterday as all the doctors surgeries were still closed from Christmas, I got bloods a urine test and an internal examination and they said everything was fine. But is it fine?

I was meant to go for an early pregnancy scan which they said they’d phone me today but they never so I phoned anti natal and they said they’d get back to me tomorrow. I am so petrified of miscarriage as I’ve had one before and I’m desperate to have this baby. I just don’t know what I should be feeling and not feeling at this stage.

Anyone else feel the same? 😩
