For fun symptoms when pregnant with girl vs boy

Second pregnancy .. have a one year old boy at home and we don’t find out the gender love the surprise.. I know every pregnancy is different but what and how we’re yours the same or different if you had two Same sex or two different… this time around I don’t crave anything and it’s killing me! I have no belly line yet and got mine with my son at 16 weeks… curious to hear everyone’s experience maybe I’ll get more of an inkling of what this baby is!=) I had a gut feeling my son was a boy from day one.. this time I’m clueless.. also don’t have a preference just a healthy happy baby! But fun to guess !
