Hey, well to start off I am 71 days late for my period. I have symptoms as tho i am pregnant but when i was 12 days late i got a negative test. My boobs hurt, nauseated, cramping as tho i am on my period, bloated a little, feel like i am not getting enough sleep, my moods seem to be so touchy here lately. I just want to know if anyone else has had this problem and should i go see a doctor about it. I am use to missing a period when i was younger but now that i am in my early 20's i have gotten use to them being on time.
