Strong positives!! Early pregnancy

So I posted on here a pic of my pregnancy test I took 6 days before my period was due, last week. The control line was faint and I had a strong positive. That happened on a first response. Then today, the day my actual period was due, I took a clear blue week estimator test and it came back pregnant 3+. I don't know if maybe I'm farther along then what I think I am even though my LMP was may 21. Or I just have really strong pregnancy hormones! I have Dr's the 29th so I have to keep myself sane till then.
