Just an update.
I stayed overnight on Thursday and til late Friday night. There was a huge cock up. Loads of doctors out for some kind of assessment thing, including the ones meant to be responsible for me, so I didn't see anyone until 7.30pm on Friday.
Apparently I had to see an obs consultant to get the referral to the neuro team, who can then do the MRI referral. None of that happened due to the above.
The neuro team only come once a week from another hospital so rather than have me sit there for a week they've sent me home and are trying to get me seen as an outpatient. Unfortunately the SHO who I saw at 7.30 (one and only time I saw a dr) mentioned that their concern is that I have a blood clot. And then dropped off a load of codeine and sent me home saying I'd get a letter. That was it 
Since then I had a medium headache Sat and Sun, which has eased off the last couple of days. But I've been really nauseous ever since. Threw up everything I ate on Sat, couldn't eat on Sun, was okish yesterday (mum had DS for me which helped, I basically stayed in bed all day) and have thrown up breakfast today. I thought I'd picked up a bug in hospital, but now I'm wondering if it's not just stress related.
I put DS down for his nap this morning and laid on my bed and cried for half an hour. I'm completely freaked out and I have no idea what's going to happen.
Part of me thinks they wouldn't have sent me home if they'd thought I might drop dead (although they said nothing has happened for 16 weeks so it'd probably be ok to leave me a bit longer) and surely they'd have given me something like blood thinners if they really thought that. But then I'm not sure.
The dr I saw on Friday night said I didn't look ill enough for a blood clot - probably true (I'm hoping so) but she saw me on the one day last week when I didn't have a headache or was really nauseous/vomiting - typical.
I'm so frustrated. I just don't know what to do. I'm so worried.
And I'm being a crap mum to DS1 :(
