Anyone used an opk as hpt? pics?

First off my pregnancy tests were sooo faint at first that I thought it was in my head. Try not drinking anything befor bed and testing in the morning. My opk tests did work as test for pregnancy too. I guess its the hcg. Read on the back of boxes of prg tests for how sensitive. Most are 25hcg but try and get 15 or 20. These worked a few days sooner for me. Good luck. Fyi, I believe your PREGNANT, I could almost put money on it. Congrats!
