Period going crazy?? HELP PLEASE!!!!

Chelsea • 21 y/o 🤘🏾 1 miscarriage 💔👶🏾 ttc 4ys

So I thought I was pregnant when I kept getting faint positives on hpt last week only to my surprise my period came on. My period is usually a normal heavy not to heavy flow. Since I can remember I’ve always had little tiny clots throughout my periods. But this month is extremely strand. I’ve had extremely little to no clots, I’m not even filling up a whole pad it’s probably no bigger then the size of a Reese peanut butter cup and it’s going off because everything is turning brownish like it’s going off. And throughout the whole night I didn’t fill up one pad it was still very tiny amounts. I don’t wanna make a big deal out of nothing but I’m a little worried of what’s going on. Oh and also I’m usually on my period for 4 days and this is my third day and I’m going off today. Please and advise will help.
