Since we've been TTC my period is pretty regular. I've seen a specialist and he says I've got <10% chance of naturally conceiving because of low ovulation. AF is due on Wednesday but last Friday and today I've had very, very light bleeding. Today I needed to put loo paper in my undie (as I didn't have tampons as it's not due till next week) but Friday I didn't even need that. We've assumed we'll need <a href="https://glowing.com/glow-fertility-program">ivf</a> (which we weren't going to start till after our  wedding) so we haven't been careful at all in terms of contraception. Could this be implantation bleeding? Help, please?!
