Is low sex drive normal during pregnancy? This is severely hurting my relationship for him and me. Very stressful

Lots of changes. Hormones fluctuate widely during pregnancy. Some women find their libido has greatly increased, where others it greatly decreases. This can also happen if you have severe "morning sickness" - it's kind of hard to be in the mood if you're feeling nauseated and throwing up all the time. Long and the short, it takes an adjustment. Take more time with each other, more romance. Good luck!
