I hate being pregnant

Don’t get me wrong I love my son and the baby I’m currently pregnant with but I never want to do this again. I feel horrible, I either stay so nauseated I can’t get out of bed or if I take meds for it I stay so constipated my stomach is always hurting and I’m sick from trying to use the bathroom because constipation is so uncomfortable for me. I don’t mean to complain but this is so hard. I can’t wait until this is over and I never have to do it again.
