Helloo frends, i have completed my 30th week of pregnancy... Bt recently there is tightness in my belly... There is no pain and also it goes away aftr some seconds... Is this normal? Y this happen?

hi , belly tightenings common in 3rd trimester

Yes it is common since the child is growing there will be stretching and tightening too. You can walk instead of sitting for long durations.

They are braxton hicks Contractions. They are your body's way of getting ready for the real thing -- the day you give birth -- but they are not a sign that labor has begun or is getting ready to begin.

relax and wait upto 42 weeks for natural labor to start. Your baby will trigger a hormone to start labor when it's development is complete.
