We're Pregnant!

I had my Nexplanon taken out the 13th of January 2017. Didn't have a "normal" AF since before I had it taken out. I thought I started 2/10/17 but it ended 2/12/17. Should I count this as a period?. I read somewhere online that bleeding for 2 days wasn't considered an "AF" So im kinda lost about how far along I am! Also, got this positive 5 days before MP 3/6/17
