Is it even possible to be expecting?!?

I’ve been tracking my period since June and they have always been on time or no later then 2 days late max!! Well today marks 9 days late I’ve taken 2 at home pg tests both negative one at 6 days late and 8 days late Both taken in evening time.... I know it would be a miracle if I were bc my husband doesn’t want another baby so he pulls out which is fine but this not period but no positive test is driving me insane.....going to re test in am... wondering if any women have had same experience but end up actually be pg?!?
