thank you for your query.
what you are experiencing are the classic side effects of luthera birth control.
a lot of women experience Vaginal bleeding between periods
(spotting) or missed/irregular periods
may occur, especially during the first 4-5 months of use.this along with clots,passage of dark colored blood is seen.there may be associated nausea, vomiting
, headache, stomach cramping/bloating, dizziness
, vaginal discomfort/irritation, increased vaginal fluids, or breast tenderness/enlargement.
i would advise you to consult your OB/GYN to change the birth control method to a more suitable one.
wishing you good health
