I had unprotected sex (however he pulled out - I know not full proof at all) in the early morning of July 2nd. I took Plan B that evening within 12 hours. I was due to get my period on July 4-6th..however all I got was light brown discharge/bleeding on July 8-10 followed by what seemed to be a regular period from the July 9-12th that was a little light, but still had to use tampons and pads.

In my 28 days cycle Ishould have been due for my period somewhere between the Aug 1-5th time period if things were back on schedule. I have however STILL not gotten my period. I did an EPT on the 5th (negative) and one on the 6th and one on the morning of the 7th. All negative. I keep spending a fortune on EPTs and after googling it I was all scared that HCG doesn't turn up in all women, but by now if I was pregnant from July 2nd surely it would be showing in my urine right?

Is there a possibility I'm pregnant after 3 failed tests?
