Need your help! Tmi question

Heather • Nursing student, raising two beautiful boys and have a loving hubby! I`m the queen of my own castle!
So I have a question according to glow I am a week late but I have a longer cycle than 28 days mine is like 30-32. So anyways I missed my period and yesterday and today hVe been spotting brownish color when I wipe. Not everytime and it's not getting heavier. Could this be implantation bleeding?? It's so light I don't have to wear a pad or tampon. Need advice on what to do !!
