SO, I've seen the doctor. He said going off my pretty much super regular cycle and another look at my blood work, I wasn't just irregularly late in February, I had an early mc. I was pretty down at the time because he had said I wasn't pregnant, he told me my bloods said no and the HPT results weren't super positive, very faint almost invisible ones, but I FELT different that month, which was why I got him to re-check the results, which at 40 days the HCG was 22 (which going off my cycle was the reason they sent back a neg result as I likely had already started losing it.
So, I'm (according to the O calendar) most fertile from 9-11apr, had me some woohoo day 11, 12, 13 so not super hopeful for this month, but fx anyway. I am getting some O pee strips so I can track my cycle a bit more closely if there's no jelly bean this month.
