Ovulation test help?!

So I’ve been testing since the day after my period (I only have 3 day periods and then the 4th day is just nothing or very little brown blood)

I have a very hectic schedule so testing at a certain time every day isn’t always easy but I’m going to test at 11am and 2pm every day from today

Just wanted some advice and reassurance really, does this look okay? Did anyone else’s fluctuate like this? Is testing at 11 and 2 a good idea?

Any help would be great

TIA x
