Pregnancy symptoms 🙏🏻 help!

Jane • Alexis Agnes Jemma Flaws 💜🌏
So I am engaged to my wonderful fiancé and we have been TTC since June 2015 after losing a baby in May I was diagnosed with PCOS in November 2015 so long story short I have the following symptoms and my period isn't due for 6 days  :
Lower back ache 
Went off all the foods 
Light cramping
& a little nauseous 
None of which I usually get a week before my period is due does any one else think I could be pregnant again! I hope I am as after losing a baby and then being told I may never have anymore I seem to set myself up for disappointment every month! But these are symptoms that I haven't ever had not even when I was pregnant before! 
Any advice is greatly appreciated 😊👶🏻🙏🏻🍀
