Late period?

Erin

According to glow I am 5 days late and bfn this morning. The problem I have is I got my nexplanon removed in April. I started my period on May 8th and I don’t really know my cycle length. Before my son I was super irregular. I feel SUPER nauseous but I don’t know if that’s my mind playing tricks on me or what. This is soooo annoying!!
