### input:
I took next choice emergency contraceptive 13 days ago, about two days after unprotected sex. About five days after taking it, I started spotting, which the following day became a heavy period with the most unbearable cramps Ive ever experienced, and I have had heavy cramps and bleeding since I first had my period.  Thankfully that only persisted for that day. But that was about 8 days ago. About 3 days ago, I had no spotting or bleeding whatsoever but started getting pretty bad cramps, as if it were the first day of my period or something, but there was no spotting or anything. Now today, which would be day nine of this period, I have spotting again, cramps, lower back ache, like my periods just starting. Usually symptoms of my period dont continue past day 3 or 4 of my period. This is technically day 9 and Im having spotting and symptoms still.  I guess it could be helpful to also mention that when I started this new altered period about 9 days ago, that day would have been day 19 of my normal cycle, had I not taken the pill and it alter my cycle. And I usually have longer cycles, 32 days or so, so if I had not taken next choice then I would be getting my normal period in about 4 days or so.Ive taken next choice or plan b before, and nothing like this has ever happened. So Im wondering, is this normal or cause for concern? Also just wondering what on earth could be going on with my body right now; Im mainly confused.

Hello, I have gone through your query and understood your concerns. If you were my patient I will advise you for an ultrasound as it is very important step to take now. We need to rule out pregnancy first which is got aborted, and it will be very important to consult a gynecologist for dilatation and curettage in that case. If not we must also rule out ovarian cysts which will cause severe cramps. I hope you will go for ultrasound soon. For symptomatic relief you can take tab. Pause and tab.mesenteric acid Thank you
