i went through your statement. The word miscarriage
is itself doubtful without confirming your pregnancy
. I assume that you had a delayed period and Folic acid
is given for anemia.
If your periods are regular - no need for investigations.
Watery vaginal discharge
is a common one.
Without any botheration continue your life. If you are particular about having a child, have sex preferably between 11th to 17th day of your LMP.
