does anyone feel like this ??!!!!

Ok so this is my last pregnancy ... I have been pregnant 5 times .. including one miscarriage and a set of twins I'm happily married I'm a stay at home mom .. we own our home .. actually two .... I am happy with my life and where it has brought me .. I have a set of twin toddlers a 7 year old and a 15 year old step daughter but for some reason I feel so uneasy about this pregnancy like oh God my fourth child , or like people would say Damn y'all building a football team I mean it's not that I care what people think ... or maybe I do .. I'm 33 years old plus the pressure to be like a size 6 in addition to being think after you have a baby ... I'm not sure if I'm venting or asking questions about other women ... I'm blessed and I know that but I still feel like it's not the same thoughts or looks as if it's a moms first pregnancy !!!
