Thanks for the query.
Some amount of pain abdomen, clear white discharge are common in pregnancy
If you are having continuous pain better to get examined once.
As your pain is getting relieved by taking liquids, continue that.
Taking plenty of water, nutritious diet, adequate rest also helps.
If you are having pain in drinking water etc. once consult your doctor and go for general and systemic examination.
