Trying to conceive with irregular-ish cycles pcos

Killa

hey guys. so i have pcos and still dont have complete control over it but i want to have a baby so bad. i dont get a period every month however when i do get it it lasts longer than a week but it always starts between the 28-31 of the month. i want to try mucinex this week as i got off my period yesterday to see if maybe it will help if i do indeed ovulate later on. any tips?
