Well don't count yourself short- you still have two applications out there. I have a wide variety of research experience but I think if your in undergrad the expectation is that you've done some research. They don't want people who've never done any research for then who knows if you are really serious about grad school or if you will stay after you start doing research. Maybe you won't like it? Just keep the faith.
With all that being said there might be different tiers of research experience. Like a strictly literature review based experience versus one where you ran subjects, collected data, and analyzed it using statistics.
Good Luck. You will get in.
