Ok this app saids I'm due in two days one of my other apps saids I am two days late. And another app saids I won't start till first week of June  I got blood work coming up and then.  I might have a ultra sound. Done.  On June. 16 for a recheck. My periods use to be very irregular at.  From Ovia. But. They have been pretty regular for about 2 years now.   Any advice.  Or is it just a waiting game
