Re: lower abdomen pain and unexplained bleeding
I am not familiar with primolut (?) but I imagine that when you eventually go back on the same pill you will experience the same problems. I don't know why the doctor recommended this to you. At the very least he should change the brand or type of antiovulant. There are many kinds of pills. Some are monophasic meaning that you have the same ratio of estradiol to progesterone during the whole cycle. Others are progesterone only and others still are triphasic which try to mimic the body's natural cycle so at the beginning of the cycle there is a higher ratio of estradiol (ie. estrogen) to progesterone and as the cycle progresses, the ratio of progesterone to estradiol goes up. There are even different kinds of progesterone in pills so even this may be causing the problem.
Not all pills work for all women and if the pill is the only option for you then you need to find one that won't make you sick. Saying, take a break and then go back to taking the same thing makes absolutely no sense at all. I personally have sworn off the birth control pill after being on it for over 20 years and then having complications from long term use. At my age (I am in my forties) I also don't want to take the risks that the pill poses. However, it is, unfortunately, one of the most assured ways of not getting pregnant and I suppose for some people it is the strongest choice. However, if it is making you sick then this is definitely a sign to either switch pills or to find another form of birth control that offers you just as much protection (I believe that only a combination of the condom plus spermicidal foam, applied correctly, can offer as high a success rate against pregnancy).
If this doctor won't help, find another one. They are not all made the same.
Take care and good luck.
