I am not sure if I am pregnant.. My period is late by about 8 days or so.. I have had dull abdominal pain/cramping for about the past week, which I thought I was just getting my period the entire times but nothing has happened, which is very unusual. I am never late. I have taken 2 tests and both were negative, but I think I may have tested too early. For some reason I have this instictual feeling that implantation happened 10 days past ovulation which would've been the 19th (just something about the way I felt that day) I have read that Hcg starts at about 5 once implantation has happened and then doubles every 2 to 3 days. I took my second test on the 21rst.. so hypothetically if I implanted on the 19th and I was at 5 with Hcg, then I would be at only 10 Hcg on the 21rst.. not high enough for the test to pick up (test reads at 25).. so, now I am waiting to see if I get my period still.. or if not then I am gonna take another test on Sunday morning the 25th.. by then I should be at 40 HCG if I am doubling every 2 to 3 days.. should be high enough at that point to read positive if I am.

But my question is relating to a possible symptom... which i dont feel that i have too many.. or maybe some I just dont take too seriously..

obviously my period is late
i have had cramping which i have read is normal do to implantation
i have been sleepy (fell asleep in the chair the other night, odd.. but I guess I could've just been tired that day)
I was a bit light headed/dizzy the other night at work (but could've been do to being hot and was getting a headache)

My breast don't hurt at all.. but they don't hurt during my period either.

Three things that happened that were kind of odd... but not sure if they would relate:

Sometimes things smell really strong to me? I was about to get a shower the other night, had the water running waiting for it to heat up, and it smelled like chlorine.. never have noticed that before in my life.

Tonight I was eating a sandwhich that I have had several times, but the onion on it was SOOOOO strong that it almost made me gag, and I had to take off the banana peppers because they were also strong and just didn't taste good to me.. normally I would've love it. Not sure if that is something, or if the sandwich was just different than normal.

And I have been wanting to drink a lot of milk? Normally don't.
