Railways — pregnant female not allowed to travel in handicap compartment in 1st trimester

I am in my 2nd month of pregnancy and was travelling via handicap compartment.. I was about to get down a t malad station when a lady from behind spoke so rudely and pushed me saying come behind.. I told her mam i am also getting down at malad station.. She again pushed me and started yelling at me saying that she is a cancer patient... What right she had to touch me when i was politely talking to her...???
To add to the cake a lady constable who was standing right in front started yelling at me when i asked why did she touch me when i was talking to her... The police constable said you cannot travel in this compartment till the 9th month of pregnancy when i told her even i am pregnant and i was polite to the lady..

Where on earth is this justified that 1st three months of pregnancy which is so crucial are not just ignored... There is no mercy shown for the pregnant ladies who travel in peak hours??? How are they suppposed to travel in crowded compartments which poses greatest risk for both mother and child???

On top a police constable behaving so ruthlessly and not saying a word to the so called cancer patient who tried being violent with a pregnant lady???

Where is the justice???
