Thanks @ specialmom. I am so nervous right now even though I know there is nothing that I could do but wait until Friday. I did test with a ept brand yesterday morning before the spotting started and it was negative but I will buy the first response and test after Friday if af doesn't come.
Well, that is always a possibility. I don't think that implantation spotting is very common but some do experience it. You shall find out in two days, right? If you want to know now, you could try an early response pregnancy test which allows you to try a set number of days before expected period. They are a bit more costly but pretty accurate. I found out I was pregnant 4 days before my period with the Early Response brand. good luck
