Miscarriage, Period, or what?

its possible for me to be pregnant... at most 2 months... at least 1 month... idk if I am or not though... I am on my period now, at least I hope its just a bad a period. Do you think I may be pregnant and having a miscarriage? I've had severe lower back pain, pelvic cramps, and lower abdominal cramps and lasting pain...along with what started as light bleeding and its gotten heavier. I started last Wed. and am still on it. I have to use pads because of cramps being so bad, and i have to change them like every 30-45 minutes...ive been really nauseous, and vomiting, ive had high fever the last 24 hours, and feel really weak. Ive also had clotty stuff coming out. Im scared this is either a miscarriage or something else wrong with me... please help me. I'm 17, and don't want to tell my mom. My doctor, I'm friends with, I've told her half of it, but haven't talked to her since yesterday afternoon, and things have gotten worse. She said, I probably am just having my first "real" period. idk

my doctor doesn't know im wondering this though. should I ask her this specifically? i am on birth control, i started 3 weeks ago, so, i started my ''period'' like 5 days early. i didn't think about being pregnant. i think what she mean by "real" period was when a woman matures more and begins having more side effects and all.
i started taking 4 Advil every 8 hrs, as my doctor prescribed, today, ive increased it to every 4 hours, and its hardly touching the pain.

I have had two miscarriages between my three children. From what you mentioned it seems as if you are having a miscarriage,especially the part about the flow being very heavy,severe pain,taking medicine around the clock and changing your pad constantly.You will have to go to see a doctor RIGHT AWAY because you need a D and C done that is when the doctor basically clean your cervix area and scrap away all the dead tissue.There are so many scenarios that could be going on with you because of the fact that you are on birth control pills and it is possible that the type of pills you have are not working for you and causing your period to be so heavy,or you could be pregnant in your tubes(you can die from that if it goes undetected),with my last miscarriage I was pregnant in my tubes and did not even know it and had to undergo emergency surgery!!!,did you have unprotected sex before you got on the pills or a few days after taking the pills? Either way,you need to go talk to your doctor about what is going on because no woman should be going thru what you are experiencing. Good luck!!!!!!!!!!!!!!

See a doctor or go to a clinic cause if you just started birth control you need to find out everything that would happen to your body while on birth control.
