Sorry but you won't get paid. I know it sounds like a nightmare coz its too close but imagine you get exactly a $100.01 this month plus your last month equals too $199.99 and then Adsense ban your account!
You will have to wait till the next payment cut off date as you aren't past the $100 limit. Think of it as a bonus the next time round!!
Well, except for the jerk above you. Back when I started adsense it was during the month (hey, who starts it on the 1st of the month!) so I only had it going for much shorter than the full 30 days...Believe it or not, I was even worse off than you $99.99 and no, I did not get paid lol
