I could use some advise

So as of today I'm 3 weeks late and I have tested but still bfn then I went to my doctor because I thought maybe my levels just aren't high enough. But still bfn so my doctor put me in medicine to force start my af so I could stop wondering and just try again on my next cycle. That was last week. I've finished the medicine but nothing. So now I'm back to square one. I'm starting to get really sensitive to smells as well as sharp pains in my left ovary area. My boobs are also getting really sensitive. Idk what to do at this point... Help
