I Took Nordette For The 4th Time Now. On My

I took nordette for the 4th time now. On my 3rd time of taking the pills, i had dark brown mens after 6 days that lasted 5-7 days. A week after my brown mens, i feel breast soreness and sometimes cramps up to this time. My partner and i had unprotected sex so i had to take nordette again for the 4th time because i became paranoid. Today is the second day since i took the last pills and i noticed a smelly/fishy white discharge even when i pee.

I discovered that Nordette is a morning after pill and i followed the 4 + 4 instructions. I learned that 1st 4 pills should be taken within 120hrs after unprotected sex and then take another 4 pills 12hrs after.

Since i've used it for the 4th time now and with all the pains i'm feeling with my breast and abdomen i'm confused and worried now. Currently, i'm waiting and hoping for my withdrawal bleeding. Haven't taken pregnancy test yet because i'm scared~

1. Did Nordette worked? Or am i experiencing pregnancy symptoms even though i had dark brown mens after my 3rd time of taking Nordette?

2. Why am i having smelly/fishy white discharge?

3. Should i stop taking Nordette now? If yes, what should i do next?

YOU'RE RESPONSE WOULD BE A GREAT HELP. I really don't know what to think now and it's making me really stressed. Thank you.
