Hello, First of all, you should undergo one home pregnancy test to confirm/exclude pregnancy as you have stopped taking birth control pill from this month. Above features with creamy white discharge is also seen in early pregnancy. In exclusion of pregnancy, other reasons are hormonal imbalance, stress/anxiety, irregular diet habit, psychological factor, obesity or extreme wt loss. In such cases, USG pelvis, complete hormonal assay, blood sugar and one vaginal swab test are needed to be carried out. If white thick vaginal discharge is not associated with bad smell or itching, then you have nothing to worry. Maintain genital hygiene properly. Otherwise it may be associated with vaginal yeast infection. In such case, vaginal suppository & anti fungal medication are needed. Avoid stress/ tension by deep breathing, take healthy diet with iron supplements, drink more water & eat more vegetables/fruits, control body weight by light exercise. Be well.
