Am I even in a TWW? Thoughts?

[zoeh]

Today is CD19. I haven't been monitoring anything at all this month, because I'm in between doctors, and the only time I've ovulated in two years was last cycle on a high dose of Femara. So I started this one with NO expectations and figured I'd wait until I can see a new specialist in January. DH and I only BDed CD 6 and 8, and then 16 and 18, because I was really sick for a week. Well, three nights ago I started having weird, vivid dreams and bloating. That has only happened to me when I've taken progesterone to induce a period and the one time I finally O'ed (starting at about 3dpo). All today, I've had light brown spotting that is only noticeable when I wipe, accompanied by very, very mild cramping. I've also been super emotional and weepy, like I normally am during PMS. This is probably just normal breakthrough bleeding, right? Possibly the antibiotics interfering with my cycle? When I first saw the bleeding, I thought maybe, just maybe, I popped an egg super early and it was implantation... but after 17 months actively TTC, I just *know* those sorts of miraculous things don't happen to me :-/, and I can't even be 100% sure I ovulated. I'm trying very hard to balance hope with realism, but it's so hard to do.
