Pregnant ?

So my fiancé and I are trying to have a baby and yesterday I noticed a bit of blood when wiping after peeing & then last night we had sex and I woke up with some blood in my underwear. Today I haven’t been bleeding when I pee, but when I wipe there’s very light blood. Could this be implantation bleeding? I have 2 period tracking apps one says I am 7 days late and eve says I start my next period in 2 days. What do you guys think? I don’t wanna take a test yet until both apps say im 5 days late.
