Ovulation test 7 days late

So I’m now 7 days late. Last month I had a weird period (I was like 9 days late, then bled for 17 days, all light besides 2 days) I had been very stressed, so I figured that’s what was going on. Do you think it’s another late period, or do you think I could be pregnant? I haven’t bought any more pregnancy tests because I’m scared I’m going to be disappointed and get a bfn, and I’ll be wasting more money (I’m typically a POAS addict lol)
