Oh wow! Now I see why it feels like there is a bowling ball between your hips. I had really bad stretch marks (never was pregnant, just was fat) I used a moisturizer with cocoa butter in it. Now you can kinda see them but they arent red, they are skin colored. Give it a try, no need to wait till after the baby is born either.
All the best <3
Ohh, Ouch! Those stretch marks look like they hurt!! You grow fast didnt you? My stretch marks looks the same way, but never got red like yours....ouch!
