bushy I have taken pregnacare or the supermarket equivalent the whole way through, the folic acid is the important one, but I was happier with pregnacare is my diet was not great with vomming and shift work.
and yep, your pee is pretty luminous! Some people find they make thrm a bit nauseous of constipated so have it with food.
Srx is a tricky one and diffferent for everybody. I was far too anxious in the beginning, then too sick then erm (tmi alert) too swollen in the outside - apparenyly this is fairly fommen, but it made it too uncomfy for me, nthst and it had bern about 4 months by this point. So thst atempt was unsecessful. We have managed once since then about a month later and thats it!
In terms of safety it really should be ok, but I could not bring myself to do it in the early months 'just in case'.
Also once I had a bump I could not stop thinking about baby, not that I yhouhht baby would be harmed, but that I felt hsppily pregnant, not sexy.
I have spoken to people who have said they felt their most sexy when pregnant. Thankfully I have a vety understanding OH, who has been ace.
if he was more bothered I would have made efforts to relieve his 'frustration' in other ways 
Have your scan tomorrow and see how you feel after that?
hope that helps, but probably not!
