Let me start this off w/ apologizing for any TMI....

I normally have 35+ day cyles and really heavy periods, but this cycle, I ovulated 1.5 weeks earlier than normal, and we DTD during that time, but pulled out.

I think I got my period yesterday (eta: exactly 2 weeks after I ovulated), but it's hardly a flow (I haven't even filled a tampon), it's dark brown and I have no cramps. I also have zero pregnancy symptoms, but I tested with a wondfu strip yesterday morning and it was negative.

What would you think of that?? Is it too late to have implantation bleeding?
