Hi Gliriel - congrats on your pregnancy but so sorry to have to suffer the dreaded ms. I had morning sickness aswell I would not call mine severe but it was bad enough, it pretty much lasted all day and all night and at one point I didnt even want to leave the house I felt so terrible - could really only eat toast and then that didnt stay down much either (still cant eat toast now lol). Mine started at 6 weeks on the dot and ended at 17.5 weeks.
Everyone is different so others expeiences are not a real guide to go by but I know you would be clutching at any hope that it is going to end soon - I was the same.

I am actually dredding being pregnant again for that reason - I hate ms.

I hope it ends soon for you sweetie.
