Pregnancy symptoms? Help!?

Hi so I am 2 months late on my period. I was on the pill for 5 days then came off it because I had a bad turn on it. I had a period that month I stopped taking it, then the past 2 months I haven't had one i have took many tests but are all negative.

I have been having some mild cramps lately very different to period ones. I have been having lower back pains also and discharging a lot, an increased sex drive, bloating, insomnia and muscle pains! I don't know if I am pregnant or not and what to do as I'm not having periods? Advice please?! X
