TTC and just got off depo

So i received my depo shot on 2/18/2019 and i was due for another 5/09/2019 - 5/19/2019. I haven't had my period since 4/29/2019 .. Have been having intercourse ever since the first day i was due for another shot.. And before i took the test when me n my bf had sex i would bleed after but not for long everytime ( not happening anymore) .. Took pregnancy test a few weeks ago and all negative .. But i took an ovulation test on the 21st of this month and as you can see it isnt as dark as the other line but isnt just a faint line ..

Also have been feeling off n on a tingly feeling inside me like my uterus n had back cramps last night . should i just wait for my period or ??
