Ohh it worked for my friend when it told her take a test she did n she was pregnant n she had sex on all the highest fertal days n she ended up pregnant .. Idk though .... And i use the ovia pregnancy n i love that app

I hate that app... it doesn't help me at all @emontesmommy ... its all false information

But to your question i never heard of that before i found out i never had any brown discharge i just missed my period so i checked and also my boyfriend was throwin up 2 weeks prior to us finding out n had morning sickness everyday

Download ovia fertility app it works great .. My friend used it when she was trying to conceive n it was spot on when she was ovulating and everything
