How many DPO did you get your BFP

This is my first month trying. I went off birth control The last week of June after my period. I used clearblie ovulation kit and had an LH surge in the 9th. I was not doing BBT, but did start that yesterday. My husband and I had sex every day during the fertile window and every other day the rest of the month. 
I have random pinching feeling in my stomach, and feeling slightly bloated at times. I was supposed to get my period on Friday- July 26. So far---nothing. No sign of AF, no BFP...not sure how long I should keep trying to take pregnancy tests. 
How long did it take your body to produce enough to hormone to get a BFP? Thanks for any help or advice!
