it sounds to me like she needs to see a doctor especially if shes still having problems because if u dont it may be to late. and the ecp morning after pill shouldnt be used as a contraceptive only for use in emergency situations u need to be more responsible and use condons, and she needs to be on birth control as well the ecp pill shouldnt be used everytime u have intercourse it can be dangerous im sure. im not trying to sound snotty but im concerned for your girlfriend if u keep giving them to her as a contraceptive you could probaly cause her to either have trouble concieving a child when she is old enouugh and ready or cause her problems carrying a child full term so plz reconsider your method and be careful. get her to a doctor also i dont know how things are in your country or not but in the us if u dont have medical insurance the hospitals cant turn u down they have to see you and theres also a form u can feel out that if you qualify will pay for your some or all of your doctor visit depending on your income.
I think she should see a doctor. Even if you cannot go you should pay. I am sorry but don't know if giving her so many morning-after pills is dangerous, but it doesn't sound good, they are not made to be used that way.
You say you are concerned about her health -- if so, you should not be using a morning-after pill for contraception, you should either use condoms or have her go on the pill or both, and frankly if you are 23 and she is 16, you shouldn't be sleeping with her. She is just one step above being a child, not capable of forming adult "consent," no matter what culture you are in or what she says. Sex without consent is ... well, there are a lot of names for it, coercion being the kindest. Please take this into account when you say you are concerned for her health. Not only what are you doing to her body, but what are you doing to her mental health?
Well this forum is a little different, we may not be alot of help to you in that area! Sorry
