Hello
Also been there and I seriously thought I wasn't going to be able to cope. it's so lonely and dibilitating. People just don't get it (unless they've had it) and just say eat ginger...gggrrrr!!!
Only things that helped me was just taking each day as it comes and trying not to think oh my god this is going to last for ever! Even second time round, when I knew how bad it was and how long it lasted, I kept reassuring it myself that it would get better by 8 weeks, then 11, weeks, then 12 weeks, 13 weeks etc. So if you keep setting yourself milestones it might help? You've got to 14 weeks, so you're almost through the worst of it now! You've done the hardest bit!
I know you're feeling awful right now, but this is when the baby is doing so much and hormones will be at their peak. You're making a baby that might live for 100 years - your body is doing so much!
I went to the doctors and got signed off work for 2 weeks and was then xmas so ended up quite a bit of time off - made a huge difference as still felt crap but more manageable when not so tired.
I found pregnancy sickness website and forum helpful too. Plus oddly an app called nevasic (google nevasic morning sickness) which plays distorted music to disrupt something which reduces nausea (apparently proven for motion sickness, chemo patients etc too). Not a miracle cure by any means but did help slightly when nausea really bad.
I also stopped taking the pregnacare pills and just took folic acid on its own instead.
Eating regularly also helps, mine definitely worse when had an empty stomach. Diet coke and very cold water also helped me a bit.
Don't listen to all the healthy eating when you're pregnant advice - just eat what you can when you can!!!
Good luck! Hang in there!
