Was this caused by stress or something else?

I'm 18 years old and I'm sexually active. I was supposed to have my period around the 7th of June, but all I got was very light pinkish brown bleeding that lasted less than a day. I thought I was pregnant but I've done 3 pregnancy tests within a span of two weeks of the 7th. Now on the 25th I seemed to have gotten my period. The only thing is that it is VERY heavy and I have a lot of clots, which is unusual for what I usually have. I've also had very intense needle like pain that feel like they are in my vagina and not where my cramps usually are. I'm wondering why this is happening? Could it be from stress? or could I have been pregnant and had an early miscarriage? What do you all think?

From what you say about the clots and unusual pain, it is possible that you had an early miscarriage. It happens more than women realize.You should be fine and not need to see your Dr. about it, unless you bleed for an abnormal length of time; feel pain that is severe; develop a fever; or any other serious symptoms, like fainting.
Good luck. Hope this helps.

If you have taken 3 pregnancy test and they all came up negative, its unlikely you are pregnant. However, you may have an STD, it doesnt sound normal. Normally stress would just stop your period if its gonna affect it. If i were you, id go to see a doctor as soon as possible. Im sure its nothing too serious, but it sounds like you need checked out.

um if that was one of your first times then it is prolly just because he popped your cherry it seems about right the symptoms your having but the main thing i would like to recommend is go to the doctor better be safe then sorry

sweetie, this is the story of my life. i have had several periods in which heavy clotting occurred. in fact, within the last year i've had two that were so heavy i was quite scared; and one of those wasn't very long ago. i know for me, the last one i had, i called my doctor and i was asked twice if i could be pregnant so i know that they thought i could have had a miscarriage. as i'm not sexually active right now, i knew that wasn't what it was. my doctor told me to double up on my birth control pills until the bleeding stopped. if you missed a period in the past or you were late, as you were talking about, it's possible that it's heavy because of that. there is also the possibility that you had a miscarriage. but don't self diagnose. call your dr. or go to a planned parenthood place and tell them what's going on. hope everything goes ok. good luck!
