Hi,
Welcome to ehealthforum,
Pink discharge along with increase in vaginal discharge could suggest possibility of pregnancy, implantation, hormonal imbalances, etc. Look out for development of any other new symptoms if pregnancy is suspected. If you suspect chances of pregnancy, consider visiting your doctor/gynecologist at the earliest for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). If pregnancy gets ruled out, further evaluation would be done to look for the underlying cause for the symptoms that you describe. Treatment as appropriate (based on examination and investigations results) would be started to help you. Consider being in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle.
Take care.
