Oh? I didn't know that the placement of placenta would have an effect to the baby birth positioning & strength of contraction? Iirc Tigerle's positioned well by week 37-ish & her birth was very easy & straight forward despite the placenta being at my tummy. The main effect of the placenta placement for us was that it masked her movements & we didn't realise what an active & strong baby she was until she came out being all strong & muscular!

About being nauseous, would it help if you grab a small bite of something as soon as you wake up, then again in the afternoon as soon as you start to feel nauseous, to stave it off? That helps me with it, at least.
And about being off sweet things, I have that too this time around. Somehow sugar & food additives leave a very unpleasant after taste on my tongue & wheat/ gluten gave me tummy ache/ gas. But through experimenting I found out that honey & non- wheat carbs don't have that effect. So for several weeks I avoided things with sugar in them & ate lots & lots of fruit & avoided most of processed foods & pasta. And had stashes of different kinds of nuts everywhere. :p
Good luck, biddy! Hopefully it'll be easy this time around. How are you doing, MKM & CC? And {{{ KC & SM}}}
