OPK HELP?!?!

April • 28yo Married 8yo💍8yo DS🤸‍♂️ 5yo DD🤸‍♀️1yo DS (born asleep)👼 & 🤰 #4🌈

I was visited by AF on the 19th of October and she was only here for 2 days. Then i spotted for like 3 days. It wasnt much, it was like a little in my panty liner and when i wipe. After that i ran to Dollar Tree and got a week worth of OPK and a HPT. I started my OPK on the 25th. the first three days only showed the control line. the fourth day the Test line was faded. Then Sunday they were evenly dark. But today the Test line is back to showing faded. SIGH. I thought that when you get the 2 lines, you're suppose to Ovulate in the next 24 to 48 hours. So...while you're ovulating, do you still get a positive? Because at first GLOW said my OD is the 31st. Now it says today. HELP?!?
