Hello, I'm 16 years old and injured my knee (I sprained my MCL and Meniscus.) The urgent care clinic I went to prescribed me Ibuprofen 600 mg every six hours. I have been on them since last Sunday. I was due for my period 3 days ago. It hasn't come yet. I still have the symptoms of my period (bloating, enlarged breasts, cramping etc..) and I'm not sexually active. Can high doses of Ibuprofen do this??? If so can I just stop taking the pills and get my period back? (Side note: I've had my period since I was 11/12 years old so it's pretty regular and lasts for 7 days. I've missed my period once before but it was only for a day.) Thank you!
