Does progesterone given as luteal phase support and amoxycillin as cervical mucus enhancer increase the likelihood of pregnancy in subfertile women receiving clomiphene citrate for anovulation?

This study is testing whether adding progesterone (to support the second half of the cycle) and amoxycillin (an antibiotic that may help cervical mucus) to clomiphene citrate treatment increases the chances of pregnancy in women who have not been ovulating regularly. All women in the study will also learn the Sympto-Thermal fertility awareness method. Researchers hope this combination will help more women achieve a successful pregnancy.
