M.T.
Hi DeDe. I also have a 3 year old son, but I had hypothyroidism and had my gall bladder removed many years before I became pregnant with him. I am pregnant again (6 mnths), and both of my pregnancys have been fine. Your gallbladder removal shouldn't cause you any problem during pregnancy (it hasn't me either time). With you thyroid, they will check it every trimester and they will check the baby after birth for any thyroid problems. My thyroid didn't cause any problems with my 1st pregnancy and my second is going well, and my 1st baby was fine, no thyroid problems. Your thyroid will probably be a little out of wack after the baby is born (mine went from really high to really low and back before we got it regulated again). I think if you feel you want another baby you should be fine if you are watched by your Dr.
