Cramping in womb after exercise- 4 months pp?!

[maria2bela1]

So I've started introducing power walking for half hour here and there to try and get this excess weight off...I've noticed every time I power walk, after or next day I get cramps in womb, I'm 4 months PP so didn't think this would still be an issue, I'm also exclusively BFing...Any thoughts?

Joining as in a similar boat.
Haven't started exercising but too much baby wearing/toddler lifting sets my cramps off and I'm pretty sure has contributed to my period arriving early this month.
I think it can be in realms of normal, after all our bodies can take up to 2 yrs to fully recover so 4 months is minimum.

Just realised the zombie thread. MN please sort as you see fit! 🙊😫😳
