So i had unprotected sex for about less than 10 seconds nd was stressing about it since that day. When my period was suppose to start i didnt get any signs of it and i started stressing even more. Now i am about a week late for my period. I took about 6 HPTs and all of them came out negative. I figured first 2 were too early but other 4 were when i was like 4-7 days late for my period. Today i went to a doctor and got blood test which came out negative too. I am having some abodminal pains especially in my right side

I dont know what to think. Other than that i have no pregnancy signs at all.
Also about 9 months ago i was in the hospital and they found a small cyst on my ovary, i never went to check that out. Could it be that the cyst is delaying my period or is it the stress? Please help me, i am only 16 and i really dont want to be pregnant.
My boyfriend thinks that im having an appendix but idk....
Please help me, am i pregnant?
