YANBU, pregnancy was not enjoyable for me, personally. I found the early stages horrendous with morning sickness, tiredness, and getting every cold going. I was also alone, from start to now.
I found the 2nd trimester hard, as I had gall stones, so I was ill during that, then the 3rd trimester was also difficult as my DD was a big baby and she would move at such a rate that it was uncomfortable and aggravated my gall stones more!
I then had 7 days of trying to have her naturally, I also found the newborn stage extremely difficult, DD is 4 now, greatest thing that ever happened, wonderful, beautiful, funny, but I wouldn't have another.
Good luck, it is worth it in the end, obviously ha
