welcome to the two week wait...lol i used a app called My cycles+ and i found it really useful! You put in your info through out the months ( period, opks, symptoms ect) and i found after 3 months of using it actualy predicted my positive opk on my ov day prediction! And was first month of using opk's so it had used info from previous months to predict my upcoming ovulation! Happned to be the month i fell pregnant too...so maybe give that i go...i did pay a small fee to get the upgraded version (you will have to go into settings to turn on the TTC settings) good luck
hope you get your BFP soon!
