Hi, I am 18+ since I am having my menstruation,

Patient: Hi, I am 18+ since I am having my menstruation, I experience pain on my lower abdomen which is normal and I take Ibuprofen every month for the pain. However, last month I tried something new, I decided to try Ponstan Forte 500mg for my pain. And it was that same month I started to experience sever lower back pain for the first time that lasts for 3 minutes for like 2 days. This pain is very painful and I am worried. What can it be? I never had this pain before

Symptoms: Severe Lower back pain during menstruation
