From what I read on line (this site and other forum), your 90 day counter get reset if you receive a REF on EAD. So for you, it means your 90 counter start from Feb, you need wait until May to apply for I-EAD.
If I were you, I would try my luck at the local office if I really need an IEAD now. Maybe the officer is in a good mood that day.
As always, you should check with an attorney on issues like this. What I said above is my understanding of it, and it coule be wrong.
