hi baiza, sorry someone hasn't replied to your thread yet

A few questions that might help out, when did your last AF start, and on average how long are your cycles, AF arriving 3 days early, could have been an implantation bleed, some get it some don't some it is just a little others it is more. But it also may be just an unsual cycle

What cycle day would you be on now? And it depends on whether you DTD around ovulation time, a few days ahead and maybe a day or so after.

What test did you use, some are more sensitive than others, for me I have found the Discover One Step or the First Response Early Detection kits were the clearest as they test for lower levels of HCG, so if you are pregnant they can be pretty reliable as on when AF is due or after they can be pretty clear.

Your symptoms can correlate with a pregnancy as well, but the real test is a postive test of BT through your Dr check the HCG levels.

HTH's
Take care xxoo
