My Husband Is Irresponsible And Don't Have Any Good Opinion

My husband is irresponsible and don't have any good opinion about girlchild .since l have a beautiful girl in my 1st pregnancy under cesarean conditions,so now I'm in 3rd&half month but my marital parents are decided that this is also a girl and they started to neglect me including my husband .

I don't want that my 2nd baby also suffer like me.I convinced my mom to get abortion but my main problem was my mother-in-law is not sending to my mother residence.I think it takes another 15days to go there.

Abortion can possible in 4th month after cesarean?
My weigh:72,
My Age:25.
My 1st pregnancy done in 9/02/2014.
Plz answer me.......
