What is the outcome of taking progesterone along side ortho tri cyclen? will it curb the side effects of the ortho tri cyclen (ethinyl estradiol and norgestimate)?

Depends: For some women it will cause a lot of spotting by making the uterine lining very thin. For some women it can cause bloating or even breast tenderness. It really depends on the reason for taking it in the first place. But ortho tri cycle contains Progesterone so often times the solution is a change in the original medicine not adding a second medicine in.
