My daughter died during labour... I wonder if you would prefer that based on your title? I would imagine not.
Agree that a change of title might benefit you.
As for your post, I think it's pretty normal to 'hate' a difficult pregancy. Agree that speaking to a HCP is going to be best - have you had your 20 be week scan yet?
HG is absolutely crap and I have sympathy for you there, as for the OC (which I assumed you weren't diagnosed with?) I have no experience of that but hopefully all of these negatives are coming to an end now?
As for the peeing, that isn't normal and definitely worth a medical opinion. I know with the odd sneeze/cough/laugh in later pregnancy I was prone to a quick leak, but nothing like what you describe. Hopefully it can be sorted, and in the meantime lots of pads.
Maybe this will offer some advice www.whattoexpect.com/pregnancy/symptoms-and-solutions/urinary-incontinence.aspx
I think from your extreme title you are at severe risk for PND? Babies are lovely but some (not all) can be hard work, and I would hate to think that this hatred (if genuine) carries on once he/she is born and not sleeping/feeding/behaving as you expect.
I would take this time to set up a really good support system if you can, learn what to expect (but whatever you read, it's not all bad! And a supportive partner is worth their weight in gold), and try and come up with some coping strategies when your feelings are this extreme.
I get that you are posting online things you perhaps wouldn't say in real life, but that doesn't make them any less worrying, and need to be addressed.
I'm also 20 weeks with my third with a scan on Tuesday. Pm me if you want to talk or for anything really.
I hope things get better x
