I've noticed for the past three months I've gotten really congested with a bad cough & stuffed up nose like is if I'm sick but I'm not . I don't have any form of std or infection I have a regular 28 - 32 day cycle just ended AF five days ago. Also for the past two months I've had a really light af which is not normal for me ? What could this be ?
