A pregnancy test doesn't respond to ovulation. Only to the hCG hormone. Unfortunately, it sometimes happens that things go wrong right after implantation. That's what happened to you; your test line first got a bit darker and then became lighter. Really tough stuff, I know how that feels. Because of that, your cycle can be a bit off. Usually, you'll get some bleeding once your test goes negative again. Hope the next round hits the mark! Strength for now, it gives you hope, and then this isn't fun.
Thank you all!! Today I'm just gonna enjoy a nice drink.. we can't change anything anyway. My period hasn't arrived yet so maybe there's still hope..
