Tender lower abdomen, thirsty, waking up really hot.

Hi everyone , I need your opinion . So it's been about 8 weeks since my last period on December 16 . My periods are never really late & if they are it's only by a week or so . I had unprotected sex a few times now & he has ejaculated in me twice on january 1st (when i was ovulating) and a few days after that he did again . Ever since then I been having signs of pregancy . To start .. A week or so after the first of January I had the pinkish discharge that I usually get a few hours before my period really starts . But I NEVER got my period . And from there it was like a new thing every week . I got period like cramps , but no period . Breast tenderness(mostly my nipples) , still no period . Headaches , but no period . I get nauseous in the morning and sometimes at night , I don't throw up though. When i get hungry now i get REALLY hungry or when i get thirsty i get REALLY thirsty One time when I was with my boyfriend and we were having sex . I started bleeding & that led to me almost fainting . Like I had severe dizziness . I thought maybe I started my period . But as soon as it came it stopped & since then Ive had clearish whitish runny discharge , some days it will be heavy and some days it's not . I've been extremely tired and emotional . & now recently I'm finding out that certain foods make my stomach turn . And some smells , smell REALLY strong but still no throwing up. It's now February 1st and still NO PERIOD. Now I mainly just get these cramps that some might say feel like period cramps and it hurts more if I wear jeans I mainly only wear leggings and sweats now because my jeans feel too tight . I dont look pregnant & only some days do I feel pregnant . Oh! And I almost forgot , some days my lower adomen will be tender to the touch and recently now I get up in the middle of the night because I get really thirsty and I live in california and its been really cold like 50 and below at night but I wake up in the middle of the night really hot for some reason . I need help you guys, help me please . I'm sooo confused :/ please & thankyou ? :)
