Officially confused. I need advice, please!!!

So about 2 weeks ago or so I bought a first response pregnancy test. one was digital and the other was not. Both came up positive. I went and got a blood test and the results were negative. I was suppose to start my period last Thursday. I'm not the type to be late for then a day. I'm 5 days late and I took to EPT test and they were a very very very VERY faint positive. my symptoms are bloating, increased sense of smell, lower back pain, headaches(only a few, I never get headaches), mild cramping on and off and I'm always tired.

BUT I'm thinking the bloating could be cause I'm about to start my period, my sense of smell could be because I quite smoking a couple of months ago. I figured the cramping was because it's the time my period was suppose to me on. I feel feel like I'm pregnant but I'm up and down with it. What got me really thinking is having have a organism I began experiencing mild cramps, which went away shortly. WTH is going on with me? please I really need some advice. Oh when I went for the blood test I was 12 days away from my expected period. I also take blood thinner. Thank you in advance.
