I had that too... I don't think it's pregnancy, but haven't gotten a full period since the light bleeding... (Had sex January 17th ish) so idk but... Maybe let me know?
I think you mean that you had "protection".
As you had sex and your partner did use protection, you will not get pregnant.
With you peeing a lot and having a spotting, it is highly likely that you have an urinary infection.
Although it is possible for some women to have a little bleed when their hymen gets broken, you would not experience wanting to go to urinate so frequently.
Make an appointment to see your doctor and take a urine specimen with you, or you can do one at the doctor surgery. The doctor will examine the urine and will see if there is an infection. If there is, there doctor will prescribe the appropriate antibiotic for you.
In the meantime, make sure that you drink plenty of fluids and especially water. 2 litres of water a day is usually recommended, more if you sweat a lot.
