Confuse and scare

I'm in a situation medically and can't risk getting pregnant I have use protection no bc just condoms, anyway I plan on waiting two more weeks but my expected period never came so normally I'm never late . Before all this happen I been getting strangely sick with everything. I was badly bloated had cramps everywhere mostly on the right side of my stomach I have no appetite and could hardly keep food down when i force myself to eat. All of this just add up to my brain while laying down playing with my baby cousin. I honestly don't know what to do so I want your opinion before going to doctor when the situation is clear. Yes I took three test (one dollar brand and two first response) one dollar brand was faded but disappear (few days later) first response both said negative. I know my only chance is blood test but I can't get it now.
