Pregnant or not?

My last period was the beginning of last month. I was supposed to start the beginning of this month. Took a pregnancy test yesterday and it was negative, but I spotted yesterday and today and that’s it. Could it be implantation bleeding and should I take another test in a couple days? I also have a 10 mo girl and I never dealt with this with her.
