I'm new to this. I was supposed to start my period on the 9th and normally they are on time. I have been exhausted, hungry, cranky....but I have a very strenuous job so it's easy to relate my work to my symptoms not my cycle. Normally I do not get any symptoms before my period, except cramps every once in a while. I've taken a few pregnancy tests (one about 9 days ago which was 5 days before my missed period , one today which is 4 days after my missed period) and they say both said negative. I didn't experience any "implantation bleeding" or cramping. If I were pregnant, would it be possible to just get negative tests and few symptoms? Are there any ladies out there that had little to no symptoms on their first pregnancy? Anything I need to look out for?

Sorry for babbling I am just new to TTC...
