6 days late and no sign of anything

I'm 6 days late. On cd 42 today. The last test I took was a digital first response and it said no - that was on cd 38. I also took a easy at home test on cd 35 and was also negative.

I thought I had a little spotting (thought it was pink in the discharge) on cd 39 so I put a cup in and nothing was collected expect super watery discharge which i have been having ALOT of recently.

I have no idea when I ovulated but according the app it would have been feb 1st. I had sex around the fertile app time but also the week before and after too.

My last period was jan 15 to 21st.

My cd for since I have been using this app have been:

July 36 days, aug 34 days, sept 32 days, oct 29 days, nov 29 days, dec 29 days

So I am not sure what to do. I have had none of my usual period symptoms like craving chocolate, sore boobs, cramping, spotting right before period.

Expect I have been super emotional. I did have some cramps with the cup in, but I'm just assuming its literally cause I had a cup in.

Also my cervix is still pretty high up, if that matters.

I have no more pregnancy tests left either. But I'm not sure when I should try test again.
