anyone TTC?

can anyone provide any insight? I came off the pill after years and started using natural cycles with my oura. not sure what my “normal” period looks like but I’ve been getting minor/major symptom alerts from oura for a little over a week and high temp alerts. I’ve had weird cramping over the past week as well not similar to what I remember normal period cramps being. today I started spotting but it’s like a brownish/pink. is my body just thrown off from traveling? am I overthinking this? my test today was negative
