Arghhh

Sarah • First time TTC. Been trying since January 2015. I am 25, partner 30.
This is my First time TTC. I am 25years old.
 I went of the Pill at the end of my last cycle.
My last period was the 13th of January 2015. I am always regular and bleed for 5 days.
My next period was due on the 10th Feb. I am now 3 days late. No sign of AF showing. I took a FRESP and got a BFN.
My symptoms are:
Nausea, especially in the morning. But is has happened during the night.
Really sore nipples
Tender breasts
CM is creamy and tacky
Frequent Urination. Even when I don't drink a lot of fluids. Cut out caffeine as well.
Soooo tired. I am a night owl and stay awake well past midnight. Now I go to bed around 7:30pm or earlier.
I'm falling asleep in classes even after 10 hours of sleep.
I am always Sooo hungry. I can eat a big meal and than maybe half an hour to an hour later I'm hungry again. Always snacking.
I'm noticing blue veins on and around my breasts.
I get cramps but they aren't like my usual pms cramps. I get cramping on my right side through the day on and off. 
I haven't been craving sweets like I normally would when AF comes.
I can't stand the smell of Vegemite or eat it anymore when I used to love it.
Brushing my teeth in the morning when I feel nausea makes me want to vomit.
I don't chart.
I use an App called Ovia and it said my Ovulation day was Cycle day 17 which would put me at 14dpo. It calculates that I have an 11 day Luteal length.
I have had no spotting or bleeding.
Any insight would be very helpful as its getting frustrating peeing on sticks and seeing negative.
