could I still be pregnant?

so long story short I had my first lletz on july 10th,I ovulated about two days before it.

hhad all the normal symtoms so watery discharge,cramping,back ache then a week later I started bleeding then few days later it turned to brown blood.

I should of been due for my period 3 days ago,I thought I started it this morning as I had bright red blood when I wiped,but its now nearly the end of the day and it just turned into brown blood again and not alot at all. 

I have had no cramping at all which I always get the day before a period.

 

even with the tiny bit of brown bleeding which feels dry and sticky could there still be a chance of being pregnant?

I really want to test on wednesday but I just dont know if I will be wasting my time.
