Pregnant or???

So it has been 42 days since my last period (I am one week late). My cycle is usually 25-32 days apart, sometimes a little less or a little more (irregular cycle). But I’ve never gone this long, and I don’t have my usual pms symptoms. I took a test after 3 days late and it came back negative. I have been getting dizzy spells and mild to medium nausea and heartburn especially after I eat. I am also an AVID coffee drinker and for the past week coffee has made me nauseous or grossed out. But I don’t know if this is unrelated.

I have been having more heightened anxiety this past month so that could be a factor?

My husband and I are waiting to get approved for insurance. But until then.. advice? Insight? Am I pregnant or is something else going on.

I don’t really know what to do right now.
