Hi, it’s okay. It took me around 6-7months to get rid of the belly, even so it’s not completely although my weight is below pre pregnancy. (I have asthma so I don’t exercise) To get rid of the belly entirely, you can only exercise to tone it out.
If you’re breastfeeding, don’t worry. It will go away. Remember it took your body 9 months to stretch… it’s only normal that it take that long to go back :)
