PLEASE HELP IM NEW AND ONLY 19

I start 8 weeks tomorrow !

So i woke up last night around 3am from a sharp pain in my stomach. I felt like i had to go to the bathroom also and as i was the pain was extreme i got dizzy and light headed.

I sat sown and felt like i almost passed out so i just tried going back to my room since the pain went down a bit as soon as i walked out the pain hit again and i dropped to the floor .

At this point i was so weak my eyes were shutting and i felt like i was dripping in sweat . My dad came running down and said i felt fine that i had no fever . He just telling me to go back into bed and not lay on the floor.

The pain lasted for about 5 mins maybe unless it felt better . I took Tylenol for the first time i didnt ever wanna take medicine but at that point i needed relief . The pain came back about 10 mins later just as bad and then went away a few mins later . I got back to my bed and i was able to fall asleep until like 5 and then the pain woke me up again but it wasnt as strong

I also winded up having diarrhea ( sorry to be gross) 😞

Now its been about 5-6 hours after all that i feel fine right now just a light cramping that i felt pretty much everyday.

I am NOT bleeding in any sort of way or anything !

My doctors is on Tuesday.
