Help!! 🤷🏼‍♀️✨

So I have been off BC since September, TTC since October, my periods have been pretty normal especially recently been getting them beginning of every month. Just had my period 3 weeks ago and will start mine next week (beginning of March) just Friday the 21st I had the runs after every time I ate..I hardly ever have the runs or upset stomach, and with that I had light brown discharge. Saturday came felt better but I was bleeding, enough to put on pad.. it was red when I wiped. I thought I started my period but no way cause they have been normal. Sunday came and I’m not bleeding at all, I feel fine besides a little dizzy, breast are slightly sore but no other symptoms.. I feel like I have a high sensitivity to some smells but don’t know if it’s just me, I don’t know what the bleeding was and what I should be thinking?? HELP!! I’m about 9 DPO
