Help with ovulation strip post miscarriage

Beth
Okay, I am 15 days post miscarriage (well, from the first day of the bleeding, which started on Christmas, nonetheless...anyway, not sure how to date it?).  
So, at my checkup this past Monday, the dr said we could, and should, start trying as soon as I got a negative home pregnancy test as long as we were ready!!!!  I waited to poas until yesterday so I would hopefully avoid being crushed by still getting a positive test....so, I got 3 negative tests!! 2 yesterday and, just to double check again, I took another this morning with fmu....all negative!!!!  
So, since I'm clueless about miscarriages and cycles following, I decided to use an ovulation strip to see how things were ging and I got this!  Is this a positive?  Or does it look negative still?  
I've had 2 pregnancies ending in healthy babies (one child is 9 and the other is 4.5)....then had this surprise which ended in miscarriage :(
We want to take advantage of the increased fertility following mc and also want to proceed quickly due to the age difference of our children!!
We were sure we were finished until this surprise...then God changed both of our hearts to definitely want to add another blessing to our family!!  
I would also appreciate any prayers or positive thoughts during this time....the miscarriage really took its toll on me.  But, I felt such a peace after seeing those negative pregnancy tests and I am so excited to try for this baby!!!!
Sorry for the entirely too long post :) 
Any advice is appreciated!!!
