I'm currently 33+6 weeks pregnant. This was my first pregnancy and from yesterday night onwards there was constant pain and pressure on my vagina which makes uncomfortable for me to move, walk and even while breathing it was paining. It was not period type of cramps, but the pressure and pain was constant. I have really bad back ache too. Was it a sign of premature delivery? Will my baby need steroid shots for lungs if I deliver after completing 35 weeks? Which week was safe for baby health? At which week he doesn't need steroids for lungs? What can I do so that I'll not go to premature labor?
