Questionable PLEASE READ

Okay so just to get it out there my boyfriend and I use the pull out method we’ve only had one mishap (which lead to me having a chemical pregnancy) (and before anyone tells me yes I know it’s not smart I’m not here for judgement and yes I know it is a possibility I am).

But on to my actual question:

I ovulated around the beginning on January and we did have unprotected sex that week more than once. However I had what I THOUGHT was my period from the 16-17th then the 18th nothing at all till the end of the day when I did heavy lifting. Far shorter than my usual periods and I didn’t think to pay much attention to the flow but I think it was about usual flow maybe a bit lighter. I’ve been nauseous off and on for a few weeks now (like yesterday nothing, today it’s back again), weird headache usually at night, cramping in my uterus area, peeing just a bit more frequently(not a lot), smell sensitivity to some things, and more tired than usual. My next period isn’t due until the 14th. I took a test yesterday that looked negative(I’ll include a picture of it). But basically would you say I should wait and retest closer to my next period? Would a positive have shown by now? Am I just crazy? Thank you in advance!
