My body hates me

My period has been really weird lately. It started a day early, I had some spotting when I wiped and cramps. Later on that day cramps were gone and no blood, then out of nowhere I got really dizzy, hot, nauseous and cramps were hurting so bad I was leaning over. Go to the restroom, just spotting and passed a clot. Today it has been light spotting, headache, nausea, cramps and few clots. My cycle has always been weird but this is just abnormal to me. To top it off, my mood is off the charts. Everything brings me to the brink of tears, one minute I'm happy the next a total bitch. No clue what's going on. Like I plan on going to the doctor next week but just wanted to see if any of you ladies had any similar experiences.
