I came to er for bad cramp pains and back ache they draw blood from me so maybe they will do a blood test
for the OTC tests you have to be at least a month along for it to show up. I did 3 home tests that were negative before i got a positive. If you dont want to wait go to the dr and have a blood test done
I would say wait another week and test again it really could be either or right now a lot of woman continue to have a pretty regular period throughout their whole pregnancy but this could just be implantation too and your hormones might not be high enough yet to show up on a home pregnancy test if you can't wait that long go see a doctor and request a blood test on your hcg levels that will tell you for sure if you are or not bcuz your body starts producing the hcg hormone 4 days after conception i hope you get the answer you want :)
