Weirdest period ever.....

So we've been TTC for 7 months and I know it can take a year or more for most couples. My period showed up 2 days early this week and has been unusually light. Usually my second day is unbearable and there's been hardly anything.....I've been reading about implantation bleeding and it says it can last a few hours to a few days, but I don't know if that's what I'm experiencing. I guess if AF doesn't get back to normal, I'll test this weekend and see what happens!! Just confused and wanted thoughts from anyone with an experience like this before! Thanks lovelies! 💕
