help!!

Chelsea
So this month is unmedicated.. after a round of femara... i had signs of ovulation right after my period and got a pretty dark ovulation test but not postive... it's cd 14 and ever since then I've been unable to barley get a line on one. 
Is it possible to have already ovulated?? 
It is normal to get a close postive in ovulation test right after period, and will probaly just ovulating late???
