Super stressed over my discharge

Bibi

For 7 days now I’ve been having some discharge that ranged in colour, from light pink to red and sometimes even orangey. My last period was on the 2nd of September and since then I didn’t have unprotected sex. I only did it once with my bf one week ago, but we used a condom and we checked it afterwards. This weird discharge started like 5 days after my period ended and it is still going on. Now I also have some slight cramps. I am really scared since I do not want to get pregnant, we are always careful. There are these apps online with doctors that give you some kind of consultation and he scared me a lot. I am so stressed because every symptom I have, I associate it with pregnancy… can you help me with some advice? The internet doesn’t really help me calm down 😅
