What to do?

So I got 2 peaks in my fertility window last week, first time using opk this month, I didn't have a normal period this time either, my periods are hit and miss weather I get one every month or not.

But my cycle is usually 35 days.

I did a pregnancy test on 22nd negative. (I kept smelling werid stuff that wasn't around, so partner said to test)

I've being feeling sick in a morning and evening for 3 days, feeling tired.

When I've done pregnancy tests in the past nothing would show until I was 2 weeks late (one I was 9 weeks late then got my period day after)

I'm not due until 5TH January

Should I wait to do a pregnancy test until I've been feeling sick for a week or wait until my period is due if I don't get it?

What would you do in my situation.

I don't want to get my hopes up I might be and find out Im not. Weve been trying a while so long ive lost count, everyone around me is getting pregnant even a very close friend that wasnt trying and ended up getting pregnant, I got overwhelmed and very emotional around her that I was strong even to hold back my tears and show happiness for her

What should I do?
