So confused about OPKs

Jessica

Ok, so I thought I had a positive OPK on Sunday, and everyone on here that commented on that post thought so too. I continued to test, and had a negative this morning, but then this this afternoon. This is a positive OPK right? So how do I know which is the “right” one, or when I actually ovulated? We’ll BD tonight, but is that already too late if I already got the positive test? We haven’t BD in the past few days either since my husband is having major stress about us flying on Friday. Sex was not happening lol
