<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am still breastfeeding my 1 year old Daughter. I had unprotected sex with my boyfriend on the night of 12th April 2013 and Morning of 13th April 2013, i took Postinor 2 emergency pill both tablets at the same time on the night of 13th April 2013. I am feeling stomach ache and ache in the lower back side. Could i be pregnant or are these just symptoms of the Postinor 2?  <response>: Hi! Possibly you are getting the pain due to smooth muscle contractions initiated by the posting 2. However, you should also go for a urine pregnancy test which may be co-existing even before having sex with your boyfriend. In both the cases you have nothing to worry about. In the first case you can to for some anti spasmodic anti-inflammatory. In the second case, the management depends on your choice. With you an early recovery.
