Married and pregnant with fifth child should i keep it?

Ok I have been married to my husband for almost 5 years we have 4 children and I'm now pregnant with my fifth I'm so unsure about keepin it I go back n forth I'm about 4 months our family doesn't know why because everyone is so damn negative talkin about the economy blah blah when all dem got 3 4 kids out of wedlock 5 bdaddies its just when you're pregnant you're having so many diffrent emotions and don't need. Negative energy I'm even clashing with my husband I'm a stay at home mom during the day/ full time student (HIM) major at nite ( family dosent know they think I'm workin a pt time job. My question is how do I cope with this pregnacy deal with family and total strangers negative comments and be happy about it I'm only considering abortion so -I don't have to deal with it but should I even care
