let's see... i had my last actual period (normal flow, length, etc.) July 17 but it was late also. 40 days between that one & the one before that.

I had unprotected sex August 2-4. I started bleeding around the 7 or 8 of August. Which wasn't time for my period. It was lighter than normal with hardly any cramps at all. & I usually cramp very badly.

The bleeding only lasted for 3 days, my periods last 6. No more bleeding since & it's September 5th. No cramps like i'm going to start my period.
I've been craving things i never liked before.

I've been tired all the time.
& my boobs are sore. & i get this fluttering sensation on my right side every now & then. (I know it's not a baby kicking, it's way too early for that)

But the catch is, I've took 3 pregnancy test, which are all negative.
I don't get it... some people say that some early pregnancies don't have alot of HCG but just enough for a blood test to detect?

...any answers would be greatly appreciated! :)
