help me

I'm not sure if I should test or if it is just my birth control. I was on a birth control for a year (pill) I started to develop mood swings and behavioral problems. I switched pills at the end of June 2017 to a lower dosage. currently I am finished with one month and did not have any spotting when changing pills or any bleeding on the placebo pills. I did have sex multiple times within that month. I did not use a condom only out of habit. lately I have had sharp cramping, dizziness, nausea, frequent urination, and eating a lot. could this just be the pill our should I test?
