Period 5 weeks late but 5 bfn's

Tia • 18. Mixed race. Happy.
Hey ladies! So my last period was 18th-23rd december.. I was on the pill but I missed a few days, then when I went on my week break, I didnt bleed. Normally I bleed after 2 days. So I havent gone back on the pill yet just in case. But this is the confusing part- I've done 5 tests. All negative. Went to the doctor, she said to wait & test again. Ive been having loads of symptoms- feeling really sick all the time!! Only vomited 4 times though. Feeling tired but cant sleep properly at night, instead I sleep throughout the day. Food cravings/aversions. Also, my smelling sense is now 10x stronger which is a nuisance!! And ive been having some discharge.. And sore/itchy nipples. I really dont know what to do! 😩
