I really need some answers, Im suppose to get my period today, i didn't get it, i took a First Response test right now and came out negative. I've had early pregnancy symptoms such as tender breast, nausea, tiredness, backaches, headaches, vomit, frequent urination etc.., and on monday [4 days ago] i was spotting, little bit of brownish pinkish blood; which i beleive they call implantation bleeding. Now, I'd like to know when the hGC starts to produce if i were to be pregnant? Can i be to early to test, if so when should i take a test that will be ACCURATE?
