is cramping normal at 4 weeks?

Sarah • Mom to a toddler girl via ivf. Pregnant with baby number 2!

just found out Friday we are pregnant… been exhausted and one day of energy then next day exhausted can’t even move hard to work. i had some heartburn last night but tonight i’ve been having light cramping. Is this normal? It’s my first natural pregnancy (i had my daughter via <a href="https://glowing.com/glow-fertility-program">IVF</a>) and i’m not used to what to expect outside of that experience (last year I had a missed miscarriage and no symptoms) happy to have symptoms but if i’m honest the cramping worries me
