Hello there,
I want to

you and apologize all in the same breath... not that we're not happy you're here, but that we're not happy how we have to "meet" you. Very sorry to hear about your loss and to hear how hard it was for you to concieve your youngest. I sure wish things were easier for us ladies!
As far as the question(s) you asked
1) October 12th given that you O'd up to 48hrs after, giving you a 16 day luteal phase max... did you DTD around then? (the few days leadin up to and after the 24th)
2) is it possible that you were pg this past cycle? sure it is, but keep in mind that cycles are usually always off in one way or another after a loss... so it's highly likely you're just irregular from your loss
Again welcome to TTCAL and stick around here lady
