7 month ls pregnant and violently sick..

[thisbabyisgoingtocomeoutatwix]

Anyone experience this? I didn't think sickness so late on was normal?
Apart from my bump I wouldn't know I was pregnant, no nausea, cravings, nothing. Yesterday I was sick for over 9 hours, exorcist style. Followed by eyes losing vision (blacked over) and ears went that way like when you're on a plane and about to pop. Only last a couple of minutes but it was scary enough.
Drinking and eating plenty and baby kicking away.
I phoned my midwife who said to come in tomorrow..

Nausea at 7 months yes, not the losing vision. Obviously baby is fine and midwife isn't too concerned if only saying come in tomorrow. Try to rest and stay calm. Have you eaten different - maybe baby didn't like it and kicked tummy in revenge

Any headaches or swelling?

I'm just not a fainter so I was pretty freaked out.
Slight headache when I lost my vision, like my skull was squeezing my brain.. Not to be melodramatic!
