👣👣💙💙michelle💙💙👣👣
Ok I have a question I'm 20 weeks and 1 day preggers should my stomach still be squishy and wobbly or should it be firm and tight because it's not I'm still squishy and wobbly in my tummy n a coworker asked why and now I'm worried. Any advice would be appreciated thank you in advance.
