Cramps during TWW but not after.

Hey ladies, sorry in advance if this is crazy. It's my first pregnancy post-miscarriage so I'm a bit paranoid. Anyway I had major bloat and cramps during my TWW (wasn't even surprised when I got my BFP, totally expected it!) but now that I'm solidly into week 4, my symptoms are done! Could this have something to do with implantation or what? Just trying to hold onto some hope this go-around. Thanks!! 👶🏼
