IB?? Help please!

N • Beautiful Nikolai born 12/29/17 👶💙 Lucca born 1/13/21🌻 In love and feeling myself 👨‍👩‍👦‍👦
I'm late by two days. I have cramps like when my period is full blown happening (had them yesterday too) and I'm only getting pink and light brown discharge when I wipe, sometimes a little dark red. Nothing on my pads. Negative test this morning. Help!
