Frequent urination

I’m experiencing frequent urination but i don’t know if it’s because i’m super anxious (after reading it’s a sign of pregnancy) or for other reason, i also kind of get a tingling in my uretra

Also last week i had kind of a weird 5 days of discharge brown/pink/red (not a period but also not spotting) so i’m even more worried i might be pregnant because i know it can be a symptom

Last time i had sex was on the 13th of may and we started without a condom but after a few minutes he put on a condom, same the week before that

I have very irregular periods (i can go without having one for months also)
