Trying to make sense of my body 😔

Victoria
So I've been ttc for about 6 months now. This month I really started paying attention to my cm. Two days before my predicted ovulation we had sex. And then when I noticed ewcm we had sex. Then a day or two later I developed a yeast infection. I have never had a yeast infection before. I'm currently 7dpo and I'm having some symptoms I'm trying to make sense of.
Heightened sense of smell (took my brother to get breakfast burritos from mcdonalds and the smell of the burritos was so strong it felt as if one was right under my nose) 
Dizziness (on and off throughout the day) 
Nausea (on and off all day, a few mornings it was especially bad, today I really haven't felt sick except for right now) 
Sharp/tugging pains in my uterus (a few days ago they were especially strong today they are very light) 
Headaches! (Past few nights I've gotten a headache, which is weird cause I typically never get them) 
My boobs feel fuller and my nipples feel sore when I rub them 
Weird dreams ( I've read that pregnant women have vivid dreams, not sure if mine are vivid or it's just in my head) 
My cm right now is super watery. Typically after ovulation I dry up 
Cravings (I had the weirdest craving for a Philly cheesesteak for like almost a week now) 
Also feel like I've been especially moody lately 
I just feel like it's all in my head and that I'm not pregnant 😔
