HELP ME TRY TO UNDERSTAND SOMETHING

Claire
Husband and I are trying to conceive.  We're going 3 months now.  My LMP was May 19-24.  According to my iPeriod app, my next one isn't due until June 21st.  With that said, I noticed a little bit of blood (6/5/17) when I wiped that morning.  I didn't think much of it and so I ignored it.  Last night I went to go use the bathroom and saw blood again.  (If only I had remembered to take photos... Ugh). What could that be?  I've always be regular.  This is the first time this has happened to me.
 I'm also in my 'green' window.  I took an ovulation test the day before (6/4/17) and noticed a faint line.  I took one the following day and it disappeared.  Could it be that I've already ovulated?  We've had sex every other day up to this point. 
Please help me understand.  I'm so lost.
