2 months missed period but no positive

Hi yall, (27F) really unsure here but I had my last period in March and didn’t think anything of it as I have pcos and it’s disappeared before however I’ve experienced strange symptoms for a few weeks such as:

-crying randomly/emotional volatility
-loss of appetite but also nausea and gagging when I don’t eat fast enough
- TMI but pink spotting after intimacy
- more frequent bowel movements which is strange for me as I have constipation issues normally
- sensitivity to strong smells when I used to be indifferent to them now I also gag at them
- positive ovulation strip test but a negative pregnancy test
- impending sense of doom

Does this sound like a pregnancy or something else entirely? Kinda scared if it’s not a pregnancy then it may be something more serious. Please help :C
