Help please

I was at a friend house and we were discussing when I was going to ttc again.  I told her I was trying to wait and calculate my ovulation and she suggested I use one of her ovulation strips.  I did it thinking it would come back negative since it's only been two weeks since my miscarriage.  Is this positive and should I really do the do?? We haven't been initimate since my loss.  I know it tmi sorry!!!
