should I have another baby

Hope

my fiancee is always telling people I'm pregnant. if when I'm not. he has 3 from previous relationships an I as well. mine are all boys ages 10,8 an 18months I little back story the youngest is his cousins son. I've always wanted 4 kids. but I had complications with the last birth an I'm 35. what do y'all think haven't been on bc in almost a year I usually get pregnant quick but so far nothing
