please don't ignore!

Not sure whether to take a test! I had what I thought was implantation bleeding two weeks ago tomorrow, then came on my 'period' on the Friday, but it only lasted really two days, didn't have bad pains at all and they're usually really painful and lasts for 5 days at least. Don't know if I should just take a test just in case but I don't want to waste money 😩😂 I know people that have  had what seems like periods while pregnant so don't know if I should or not!
