Usually we do not prescribe Ortho Tricyclin to control bleeding after intercourse
. We do thorough clinical , Per speculum, and per vaginal examination, PAP test, Hormonal
test , blood tests to rule out Coagulation or bleeding disorders, and USG ( Scan) of lower Abdomen. Once we establish the cause for bleeding, then we treat accordingly.
In fact it is the contraindication to use Oral contraceptives in undiagnosed vaginal bleeding. I am sure, your Doctor must have given you these pills after ruling out any other cause for your bleeding.
You may try Primrose Oil for your mood and emotional disturbances before period.
