I am 39 years old and my wife is 32 years, we had our 1st child 4 years ago, she got pregnant sometime year but we lost the baby due to swollen legs which doctors claimed it was pre-emclaysia. She was operated on (CS). But since then no luck at all. we have tried series of methods and approach, but no luck. Of recent we were advised to use erythromycin, Can this drug be of any help? She has done a test and as confirmed okay.
