Hi, I would advise to go and see your doc to check for peace of mind. I also had pinkish/brownish discharge around the same time, coupled with cramps and low back pain which were more intense than usual. I ended up going to A&E because I was worried and thankfully the doc said everything is fine. I was actually told to only see the doc if the flow is heavy (like if it soaks a pad) but I didn't want to take the risks :)
