What a pain in the...!

So, this thing called implantation. How unfair is it that the tell tale signs are pretty much exactly the same as pre-menstrual symptoms?! As if the two week isn't bad enough without confusing it with this! Today I have what feel like period pains, 9 days after ovulating and 5 days before my period is due. I'm trying to convince myself that it feels a bit different from normal period pains... But really and truly, it doesn't!
