Help me please

I’ve been trying to conceive for a minute now I just got off the shot in august and June was my first ever time getting it but this month my period still haven’t showed up could it be from the break through bleeding when I was on the shot or could I be pregnant I took a test it says negative but I had to dip it in my pee 3 times for ot to even work plus a week or to ago I felt like I owed on myself but it was just a bunch of watery discharge ig
