I Fixed The Non Hormonal Cool Four Months After I

I fixed the non hormonal cool four months after I had my baby. My baby is now 13 months. Ever since then, my stomach has been growing big and now I feel so embarrassed because the stomach looks like I am 8 or 9 months pregnant and I wear size 14 dress. I am not a big person but the stomach keeps protruding and bulging out. Can it be as a result of the coil.
