Am I Pregnant?

The first day of my last “actual” period was September 3rd, 2017. In October , My period was 3 days late, it was a heavier flow for a day and a half, then very light for 2 days. I’ve been dizzy, nauseous, feeling a pulling and tingling sensation near my ovaries, I’ve had an upset stomach, mood swings from hell , bloated and I just feel different , I’m breaking out , light cramps that aren’t painful they’re just there.. all tests that I’ve taken are negative, I’m confused and wondering if this has happened to anyone else.. 😕
