A current study conducted by the university of North Carolina investigates if intermenstrual bleeding has an effect on a woman’s fertility.
The chances of becoming pregnant during a cycle with intermenstrual bleeding are indeed lower compared to cycles showing no irregularities. However the likelihood of a pregnancy increased significantly in the following cycles – meaning that total fertility remains unaffected by intermenstrual bleeding.
The bleeding can be problematic for women wanting to become pregnant if:
- the cycle is particularly long (> 35 days)
- intermenstrual bleeding occurs frequently
A lot of women are familiar with occasional bleeding – the most common reason are hormonal irregularities, for example if the contraceptive method is changed, but also during vacations or stress. Especially spotting is usually harmless.
Women suffering from frequent intermenstrual bleeding – especially combined with abdominal pain – should seek medical advice from their gynaecologist!
