Sorry I'm bad at explaining. But my last period I bled 5 days but it was different in other ways from a "normal period". That was March 25. And I haven't had sex since. I used two apps (1 was glow) to track my cycles and any days of intimacy for a few years. I'm 99% certain we hadn't ddd since before that odd period. Period before that was Feb 22. So Feb should be the dates I base due date off right?!
Tell me I'm not crazy for thinking I'm 9 weeks and due around thanksgiving instead of 5 weeks and due around Christmas.
