Hi there ~
I understand your concerns. I think your question has inadvertently landed in the Men's Health section. I also think that you might do well by taking the morning after pill at this time. Since there has been a slip up it might be helpful to have a urine pregnancy
test to allay your anxiety
. I also believe that you might do well with visiting an OBGYN
for having a pelvic examination as well as a PAP smear
to know why you are having the pinkish brownish discharge. Also other tests may need to be ordered per the expert opinion of a gynecologist. I hope this helps.
Take care and have a lovely day!
