Twins?

I have been reading everything I can on the internet but just looking for more people that had this happen... First day of my last period was May 1. "Practiced" on May 9, 11 and 13th. Big Fat Positive (Very clear and Very quickly) on the morning of May 24th. Took another test May 25th in the afternoon just to see again, and once again, BFP.

I can't believe that I tested positive so early. Could it be twins? Or am I just one of the lucky ones to test early and get a BFP?

I have had one successful baby (will be 2 in two weeks) and 3 M/C since I had her.
