Vvf line... Not 100%... But killer pain!

I did an ov test this morning and it came back positive because I'm four days Late. I have NEVER NEVER EVER had a positive ov test (even when in ov week!) so I went crazy! Run to shop bought more tests and I don't know if it's my eyes but I think there is a vvf line on a proper PT. but I would never have thought because I have such chronic period (well what I thought was) pains... In my lower tummy. I'm gunna do another real test tomorrow but I couldn't see any related posts. Is this normal to feel like I'm having an actual period? Thanks for your help and advice in advance.. ❤️❤️
