Many times if people do not know the answer or do not have personal experience (which is what you're asking for) they will not answer. You also asked it 8 hours ago, which EST would be at 4am. Very few are on at this time. PST that would be 1am, and again is a time many are not on.
Personally, if you have a thickened lining and follicles I would assume you are ovulating or will be soon. If that's the case, no you wouldn't be pregnant. However, without further details it's hard to say. When was your last cycle, when is your next due, are you undergoing fertility treatments?
give it a few more days and then re-test. It could just be too early for the HPT that you are using. What cycle day are you actually on?
