weird taste in my mouth and my nipples are sore?

Hi, and thanks for your query on eHealth forum!

Sore breast and weird taste in mouth can also be due to morning after pill. However, it can also be due to pregnancy. Morning after pills can delay periods, and if taken after 48 hours of unprotected sex, can cause pregnancy. So wait until after your nxt period due date and take a pregnancy test if you miss periods. If it is negative, wait another week. You'll probably get your periods. If you do not, take another test and consult your gynecologist. Hope this helps. Take care!
