Ha! I know exactly what you mean .. I'm almost out of resveratrol, multi-vits, pycnogenol and something else that escapes me that's just as expensive (can't believe the price of resveratrol, something like £22 for a month's supply!) and I don't get paid for another 9 days :( Too much month left at the end of the money!
Sorry to hear about the bipolar ... I tell you, those hormones have got a hell of a lot to answer for. And stress of repeated miscarriages, even if you physically bounce back each time they do have an emotional impact with a much longer reach than people expect who haven't been through the same, I think.
Have you got a date through for your lap? If nothing else it will reassure you that all is well inside - or else provide you with something to look into. Either way, you have another piece of the puzzle - for me, all information is vital, whether positive or negative; at least you know a bit more afterwards than you did before, IYSWIM.
