I have pcos and only in the recent months have my periods returned. Usually every 5/8 weeks but fairly regular anyway. This month it has come on bang on 28 days after last. This has never happened before in my 20 years of having them. It sounds silly asking but is this normal for pcos? I know they can go back to irregular next month or stay regular but I didn’t expect it. TMI but it is very heavy, need to change pad more regular than usual, but no usual cramps etc. Anyone else had sudden regular periods? Have recently had flu and lot of stress at work so would have expected a delay if anything.
