Hi , im in 5th month..I feel too much pain in my pregnancy in stomach,back, hips (while sleeping) . as my digestion system is already weak and I'm unable to eat properly bcz I get too much acidic that's why I feel more pain in stomach which radiates to back.. taking calcium iron and ecospirin..just wanted to know are these tablets create more acidity? and is there any painkiller safe to take bt the big question is how many days we can take it ? as I get tired of bearing pain every other day and I don't feel energetic to do anything and eat properly
