Help!!

Okay guys so I have this ovulation app on my phone and another one. this 1 I've been using for about 2 1/2 months the other I just started probably the end of October. I started Clomid for my first time Oct 27th took the 5 days of 1 st dose 50 mg... both of my ovulation apps are pretty accurate with my fertile window and I took opk's too but this app says I am supposed to start my period on the 23rd but my other one (that has seemed fairly accurate and has been good) said I am supposed to start tomorrow... I don't know what to do or think but I took a pregnancy test 2 days ago it was a BFN :-( :-( and I took another one today and it was another BFN:-( :-( I want to find out as soon as possible I'm very anxious but I don't want to continue testing early and being very let down... Would you guys do??? would you just wait it out or what would you do??? please help I'm driving myself crazy!!! Thanks so much!!!
