Implantation bleeding


I am 33 and a TTC newbie. This is my 4th month trying and have been feeling pretty discouraged. AF is expected in 2 days but I had some spotting today that was different. Often my bleeding is dark red accompanied with cramping. Today it was light spotting and bright red. Is this implantation bleeding? I will find out when I take a test. I'm too nervous that it will be a BFN again. 🤞🤞🤞🤞
