Hi,
Welcome to ehealthforum,
The increase in vaginal discharge could be due to high dosage of hormones contained in ECP. The altered smell, color, consistency of vaginal discharge could indicate vaginal infection. Do not ignore your symptoms. Visit your doctor/gynecologist at the earliest for examination and vaginal swab/smear test to confirm/rule out infective cause. Treatment as appropriate (based on examination findings and investigations results) would be started to help you control the symptoms. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet. If infective cause gets detected, and if you are sexually active, it is important that you get your partner also treated simultaneously to prevent chances of re-infection. Avoid sexual contact/intercourse while being on treatment. Avoid vaginal douching, or use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes. Avoid sweat accumulation in the area, and keep the area clean and dry. If you are not ready for pregnancy, but intend to remain sexually active, you should consider getting started on suitable regular birth control measures to be protected (after your periods). Avoid unprotected sexual contact within 2-3 weeks of getting started on hormonal contraceptive (as most of the hormonal contraceptives start giving you effective protection after 2-3 weeks). Be regular with birth control use as instructed. Avoid having unprotected sexual contact if you are not ready for pregnancy.
Take care.
