6 weeks 3 days cramping

Andrea • Momma of 1 👧🏼 March 19- IVF-fresh transfer= miscarriage @8 weeks. July 19- 2nd IVF= 🌈👶🏼 Due 4/2!

I am 6 weeks 3 days and having some pretty bad cramping today. Been going for about 3 hours now. Not bad enough to double over in pain or anything but pretty painful. Think this is a bad sign? I’ve had little cramps here and there since the transfer but these are a little worse and more constant. Thoughts? Anyone else experience this?
