Hello. I Hope Someone Is Able To Help Me. Here

Hello. I hope someone is able to help me. Here goes:

I got my period on sept 19th it ended on the 25th. my ovulation day was therefore scheduled for the 5th Of October.

Days I had sex:
- sept 25th (unprotected)
-sept 28th (protected)
-Oct 9th (protected) in sea water

On Oct 11 I took a morning after pill.
The next day, I got white creamy discharge... Not much but I haven't seen that amount before.

I'm suppose to get my period on the 19th of October....I'm scared. Need to know what's happening or what could happen.

Should I look out for pregnancyif i dont get my period?
Please let me know.

Thanks.
