Hello, I'm in my week 13 and have the same brown discharge as you. I went to KK A&E last Saturday, and after having progesterone pills for 6 days , I noticed my brown discharge coming back again the past 3 days. I went back down to KK A&E today they did a vaginal swab for me and do a ultrasound to check on my baby. Currently waiting for the result to see if it's vagina infection. I was told that red or pinkish colour should be a cause of concern. if you are worried you can check with your gynae.
