My period

So this is so TMI and I’m sorry, but I’m on my period right now, it came right at the scheduled time but it’s just weird. There’s like no blood? Just every so often a little bit of light brown comes out, it’s like kind of dischargey but not really. Idk, like I said it’s weird. Does anybody know anything about this? I googled it and it just said that it happens towards the end of the cycle but this isn’t as dark as that, and it’s my third day of this
