TTC for five years now

We're TTC'ng for f8vr years now and Only this year we start taking fertility pill (clomid)and this month will be my 8month taking Clomid.I've read a lot of good result of pre seed so we bought and tried it this month.

My concern is this month about 23days from my LMP I noticed minute blood when I wipe after pee and had mild cramps for about 3hours on that day and that's it !I never experienced this before...

I was hoping it is implantation bleedingbbut I know there could be a lot of cause to bleed too..

Does anyone experience this and it's POSITIVE?
