Will Taking Postinor-2 Worsen Abdominal Pain, While Having Recurrent UTIs, And An Episode Of Bloody Discharge After Sex?

Hi, I have been having abdominal pain. Bad sex with my husband yesterday and had a bloody discharge afterwards. I have been having recurring UTIs to a point I got scared of cervical cancer. Did a papsmear and it was negative. So I don t know what to take to stop this UTI completely. And I wanted to take Postinor 2 but I am scared it might cause the abdominal pains to increase. What should I do??
