ABNORMAL PERIODS!

Alright! Who loves abnormal periods?! NOT ME. 👎🏼 I'm going to explain what's been going on DOWN THERE 🍑, try to keep up. Because it's my own vag and I'm totally (kinda) lost. So Monday, I started and it was normal, super tampon like always.. 💁🏻 for a whopping 3 days?! Like, WHAT? Okay so, now it's Sunday and I have (TMI WARNING WARNING WARNING) -just kidding it's not THAT gross.. brown discharge.. 😒😕 and some slight pink blood/discharge? I already have an 11 month old, totally planned I swear, I'm married and last pregnancy I didn't have Inplantation bleeding. Could I be pregnant?! 🙊😀😊🤗😍 I'll sit here impatiently and wait for an answer.. 😬 HAS ANYONE EXPERIENCED THIS!?
