Ok are you guys sick of me yet?!

So the other day (2 days ago?) I posted pics of what I thought was a close to getting a positive OPK, it was pretty dark but not quite there yet. I still have HCG in my system, 43 count as of last Friday (14th) and I am awaiting my results from the blood draw yesterday. So there was some mention of maybe the HCG was making it darker then it should be. I took another one today and the test line was SUPER faint, like probably 3 times lighter then the one I had 2 days ago. I'm inclined to think I may have gotten a positive on the OPK had I tested yesterday because I doubt that if it were my HCG levels making the test line darker that they would've fallen THAT much to make the line so much more faint. But if I had gotten a positive yesterday, would the line be extremely faint today? sooooo here's my questions:
1- After you get a positive on the OPK, the next day would the line be a LOT fainter, or would it gradually fade as the days go by?
2- If I would've gotten a positive on the OPK yesterday, does that mean today or tomorrow is probably O day?
3- Do I make sense? Are you cutting me off from asking OPK questions anymore? lol
Thanks in advance!
