<s>[INST] Heya,Im a little worried I had an epidural steroid injection in my back abound 7 weeks ago, I was on my period at the time. I am now 2 weeks late, ive had tender breasts and nipples, lower back pain, heartburn, headaches, nausea and a lot of pain in which seems to be where my ovaries are. I have pcos, I am sexually active but have never been pregnant before. What could this be?thanks [/INST] Hello. Thanks for writing to us. The delay in your periods could be due to pregnancy or PCOD. It is not related to the epidural steroid injection that you had earlier. You can get a urine test done to find out the pregnancy.I hope this information has been both informative and helpful for you. Regards, Dr. Rakhi Tayal ,drrakhitayal@gmail.com </s>
