Hi, I don't have a lot of girl friends to seek advice from.

My last period started Nov. 22 and ended four days later. November 30th i had unprotected sex with my boyfriend and I'll admit I'm pretty stressed out but I've been really exhausted lately, and I've been getting migraines/headaches; which is very unlike me. I also had the lower back aches, the chills, breast tenderness (the ladies NEVER HURT), the constipation, and bloating, and the crying spells. I usually am a very even balanced person. Which led me to believe something was the matter. So i took a First Response PT. Which i thought it came up inconclusive. The second line seemed like an evap line, so I assumed it was negative and tossed it.

Then December 20th rolled around and my lovely Aunt Flo didnt come to visit, December 21st.... December 22nd Aunt Flo didn't Ring so I went to safe way and got a Generic HCG test. It had blue dye, i actually didnt know anything about blue dye tests until after wards. The test had a very thin blue line. So thin you need a bright light to see it. Prob an evap line but im not sure. 

December 23rd I woke up at 6am to cramps, I am one to have very painful cramps during my periods and clots ( sorry for Tmi) But just my mom told me she had her period when she was pregnant with me so I decided to take the second one just to see if the one i had taken before was just a bad one. And this one had a fatter line, much more prominent and you can see it with out holding it up to the light. its not BRIGHT, just lightly visible, My question is should i worry if I'm experiencing a heavy flow, and dull cramping in my lower abdomen? Could it be possible to show higher levels of HCG 2 days later even if im on my period? I was expecting the test i took on Dec 24th to be Neg For Sure, now I'm just confused. Could I be miscarrying?
