This may be a stupid question about testing pregnancy tests but... please help!!

So I'm trying to get pregnant and hoping to god I am right now after losing a baby in the end of November! I know your not suppose to test early but I did twice!!! Once at 7DPO which showed a slight very faint positive! I also tested this morning at 10DPO also saw a slight very faint line but it was more faint than the first! I know implantation doesn't start till around 6 days or so! Could this be a reason the line color has lighten? Also AF isn't due for five days and I'm going crazy! I just want to know if I'm pregnant or not! 😅 I just want my rainbow baby already.. Does anyone think I could be pregnant or am I losing my mind? I plan to test the day of when I'm suppose to have my period or the day after?! Any Advice?! Please be sweet.. I'm really emotional about this after losing my first baby! Thanks to anyone who comments! It's much appreciated 😘
