Lol yes I've heard sex and that fun little fact about sperm. I think I had a few too many rlt yesterday, I also try and apply the no liquid after 6 but then I'm sooo thirsty I'll reach for something other than water like.... Coke! (bad) then I'll overindulge in water, then it's peeing all night all over again. What I'd give for an unbroken sleep.
As for back pain have you tried going for massages and then using the heat pack? While I was working I had major pain with my sciatic nerve and that helped for me, now I've finished don't get any. Such a relief!!!
And heartburn, Aghhh eeeek!!! Mine decides to come at the worst time......during sex.. It's horrible!! I had the chewy lollies, I like them best. I tried gavascon and it was disgusting!!
