Need help

Danyelle • I`m 31 with 2 kids I`m married to my lovely husband who I`ve been with for 9 years

Hello

I had a period this month on the 6th and it lasted till the 10th of this month

So I happen to go to the bathroom yesterday witch was the 25 of this month and when I went to wipe I happen to notice dark red and brown blood witch took me for a shock because i had already had and period this month but its not like an normal period its really light and its only when i wipe nothing gets on the pad and as of today its still the same should i be worried or is there a possibility that I might be pregnant

What should i do take a test or wait till im done bleeding or take one when i supposed to get my period next month on the 4

Please help me thanks in advance
