Myturn hugs my darling. Take this time to just be. I too thought I just had to get pregnant and bang when it happened I just expecting it all to be belly rubs and glowing! I didn't expect to feel awful all day every day.
Here's the thing .... When bub is here none of this stuff really matters. You are doing the best you can and beating yourself doesn't help.
Eat what you can when you can, rest and let your body get as much rest as you can
Hugs xx
