I Had A Sexual Encounter On Day 24 Of My

I had a sexual encounter on day 24 of my cycle and normally have my period by day 28. It is day 29 currently. My partner did the pull-out method, and I took a Take Action pill 16 hours after the deed. So far I have not gotten my period, and I am very bloated and feeling like it is coming.
However, symptoms of the morning-after pill and PMS are very much the same and I am becoming increasingly concerned that I may be pregnant and have been stressing over this all week.
