Trying!

So me and my husband are trying for our second baby but we've been trying for almost 2 years now and nothing! My LMP was may 28 and ovulation was the 11th. Im only three days late, can I test? I've had bad acne and nausea but also some lite cramps (which we are not happy about because it might be AF) so I guess my question is to you is, could I be pregnant? How soon can I test? Thanks mommies!
