I got some lines on my opk 3days ago yesterday started to fade and today almost gone my ? is why did I have pains yesterday and sore breast today and also allot of really creamy lotion looking cm awhile ago? I don't know what to think

If you're positive line was 3 days ago, you could have ovulated yesterday, which may account for the pain. A positive OPK means you're going to ovulate in approx 24-36 hours, it doesn't mean you're ovulating right then. The sore breasts could also be a sign of ovulation aswell, some women experience it. The Creamy CM could be a number of things, if it's stretchy and watery, it could be your EWCM, but just in a cream colour. Have you BD much in the past few days? Sounds like this is your time.

Best of luck for your TWW.

I bd on the 2nd 4th 7th and today think I caught something?

i think you bd on the right times !
good luck!
