On the belly when pg a few years back it showed girl boy girl, With the u/s it showed twins, not long after (a couple of days) I went thru a m/c, and I would place it over my belly and it showed three then as the bleeding got heavier it showed two over the belly, after the D & C showed nothing. Afterwards found out that my Aunty was pg with triplets and m/c one to have twins back when she was younger. She had multiple sets of twins.
