TTC & OPK!

Hi everyone! This is my First time ever TTC after coming off of HBC and a little confused with OPK testing. Is this considered a positive? My line looks very dark finally, it was very faint on Sunday. So faint it had me worried. This was around 8pm last night, and I also noticed a lot of EWCM a little after. I’m new to this, and really wanting to make sure I am doing all of the right things to have the best odds of conception!
