it could be that your cycles are still sorting themselves out......then again, it could be implantation bleed...?
i'm no expert on the latter, i think some people get them just after conceiving, whilst others get it around when

is due.....
3dpo might be a bit early to test though......some people test at around 10dpo.....
really hate saying this, but you're now in what is known as the 2ww (week wait)......
keeping fingers crossed though....and wishing lots of baby dust your way too...
luv & hugs
