Scared to find out if I'm pregnant!

Ok ladys....so around June my husband and I decided to get a separation and went our separate ways. Around September we started talking again about how we missed each other and being a family since we have a son together and decided to try working on our marriage again. I had my period at the beginning of October like normal but I also had some spotting mid October. Supposedly AF was gonna come at the beginning of this month.... however it's been 8 days and nothing. (Mind you we weren't using any BC or protection because we never have). Now I'm wondering if I should test or could my period have gotten messed up because of the spotting mid month??
