I need a refresher!

[MsMayy]

I'm ttc number 3 and with dd being almost 4 I'm a bit of a novice now with opk's etc.
I stopped bc this cycle (so first month off) had a normal period etc.
I did an opk today which came up with a line a smidge lighter than the control maybe half lighter if that makes sense? That means its a negative doesn't it?
Also when I wiped after going to the toilet I had a little blood so not sure what is happening! Is it just my body coming off the pill?
Thanks!

Hi
Good luck with your TTC journey.
Alot of ladies dont get great readings with opk's but they do say it has to be the same as the other line so if its lighter then its a neg.
Im not sure about the bleeding sorry, it is probably your body.
