I think I'm pregnant..please read and respond

Fajr
I Haven't had a period since 10/27/16
All pregnancy tests have came out negative but I've been trying the ones with blue lines.
Also, my stomach randomly feels funny all the time, I have sharp pains on my sides, back hurts, it takes me awhile to get wet when trying to have sex, sometimes I get dizzy ands nauseous and I can sleep all day if I allow myself.
Any input ?
I really don't want to pay for a doctors appointment and it's just my cycle being wacky.
I'd love to be pregnant btw but I'm not gonna get my hopes up.
