Please please comment and help me.

Alright, so im in a huge ass pregnancy scare and I need help! On october the first I had unprotected sex.

Well, on october the 30th I started what I think was my period but im so scared that it was actually pregnancy bleeding...

The bleeding lasted 5 days. Was bright/dark red. Had clots and was a medium/light flow.

I have not had sexual intercourse since october the 1st.

So i kinda shrugged it off until now. Today is one day AFTER my predicted ovualtion date and im cramping somthing fierce in and around my uterus and having muscle spasams in and around my uturus. The cramps are usally mild but ive had a few severe cramps here and there today.

Along with yesterday ( my predicted ovulation date ) I randomly got sick and nauseated. Felt really hot and like I was going to faint. The sick feeling only lasted about two hours and then vanished without a trace. It was like one second i was sick and couldn't move then the next second i was 100% fine.

Im only 16 and really freaking out.. this scare has struck the fear of god into me. I am not able to get a test due to situations id rather not discuss.

Is there any possibility I could be pregnant? Or am I 100% not pregnant?
