Positive ovulation test before AF


I’m due AF in 3 days, and ive just got this? When I took ovulation tests on my glow ‘fertile’ week they weren’t as strong as this!

What is going on??

I’ve been having sore swollen nipples, back ache, nausea, headaches, indigestion and major bloating for the last week or so! Could this be a sign for pregnancy or what I don’t know! I’m so confused TIA 😘
