Cramping - How much is normal??

V🌻

I had a miscarriage in November and found out I am pregnant again last week.

I am 4weeks and 4days today, I have had none stop dull cramping all day and night for the past 2 days. I’m so worried, how much cramping is normal? I also had a bit of light brown discharge yesterday morning, which I know is old blood and normal. But the cramping and discharge together have me so scared, I can’t lose another baby 😔 help me with your experiences please ❤️
