Yes its normal. Its due to hormonal changes in Pregnancy. Deepthi & Amita, Relax & Enjoy your pregnancy.

Ya even I'm 27 weeks pregnant.. even it has happened to me also.... I hope it's normal

Thanks all.

It wl happen, its part of pregnancy... Its ok use bio oil.... It wl go once u r thru wid yr pregnancy...

This happens.. even my navel area has become dark.. the whole tummy will not be dark though, just stretch marks. don't worry, my gyn says these will fade away with time, just keep the area well moisturised.
