Has this happened to anyone else ???

So my husband and I have been trying to get pregnant for around 5 months and nothing yet. My period is supposed to start this coming Saturday but I’ve been have some random light spotting already and I’ve never bled in the middle like that. Could this be implantation bleeding? I just don’t know if that can happen a week before you’re supposed to get your period or if anyone else has experienced that. I don’t plan on taking a test until after I’m supposed to get my

Period but I am very curious
