Hello and welcome to HCM.
Thank you for your query.
A pink discharge is usually the sign of an infection, and this will have to be clinically and laboratory confirmed. Please visit your doctor if you experience any symptoms.
You have conducted a pregnancy
test a month ago, this is ample amount of time to get pregnant. Please purchase a urine pregnancy kit, which will help in detecting pregnancy.
The best time for taking this test is around 2 weeks from last sexual contact, and on the 1st or 2nd day of a missed period. An early morning urine sample would be best for an accurate result.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
