So my period was due on Monday (yesterday) but that's not the problem, the problem is, that this morning I woke up feeling slightly sick in the stomach, and at 7am it started. I had to leave my breakfast half eaten and run to the toilet.

I sat on the toilet wishing that I would poop but I physically couldn't, I think I was constipated because a little bit of water loosened things up.

But before I managed to poop, I was writhing in pain on the toilet, I was incredibly dizzy, my breathing was short and ragged, I was LITERALLY DRIPPING in sweat, my PJs were saturated in sweat, I had to call my dad on my phone from another room because I could barely talk, and when he saw that I called he found me in the toilet retching in the empty sanitary bin (nothing came out). He had to bring me a hand towel that I put across my thighs so I could lean forward and rest my elbows on my legs without slipping from the sweat.

After I managed to poop, I physically couldn't even change my clothes, I just went out into the main room with the leather couch and the air conditioning and laid there in fetal position from about 8am to 10am unable to move in fear that it would start again.

Some of you may say it was my period but I'm not bleeding yet and it is a day late.

Help me cause I want to make a doctor's appointment and I want to at least have a possible idea of what it might be.
