I was not diagnosed with HG, but wanted to let you know you certainly are not alone in feeling/thinking/saying things like you don't want to be pregnant! I have severe nausea/vomiting but my doctor never mentioned HG. I was only in the hospital once, was on two anti-nausea meds (phenergan and diclectin), but did NOT lose weight. The meds kept me from vomiting much, did not touch the nausea but my body seems to respond to my being sick/taking meds by clinging to every ounce of fat I consume, even if it was just chicken broth!
During my weeks of severe nausea/vomiting (stopped meds at 20ish weeks, but nausea remains), I cried too many times to count and told my husband repeatedly I did not want to be pregnant, and I was completely unable to think of the baby as a baby. When I got through the worst of the nausea and became less foggy, I was wracked with guilt for my thoughts but everyone has assured me and I want to assure you- you're not alone and its okay to think that!!! I no longer feel guilty and I'm absolutely delighted to meet my little man soon. Feeling so severely sick just wears on you and takes you into an ugly, black mind space. I hope you find relief soon!
