So I was supposed to have ovulated sometime during the week of the 17th in March. I took OPK all week & the following week just to get BFN on all of them so I came to the conclusion that I didn’t ovulate at all during the month & AF just wasn’t going to show up. I thought I was right until today around noon, I noticed super light pink discharge. I thought it was weird since I didn’t get a positive OPK. Just a few minutes ago, I noticed the super light pink discharge has stopped. What could be going on ?
