I'm 38 & still breastfeeding my 2 year old (including a couple of night feeds but he doesn't have masses of milk overall). Periods have been back for about a year - the first few were very irregular but for the last 6 months or so they've settled down to every 25/26 days which is more frequent than they were pre-pregnancy (used to be 30-32 days).
I'm also getting 5 or 6 days of heavy bleeding followed by at least of week (sometimes more) or very light bleeding (mainly brown/pink stained CM). I went to see my GP about it 3 months ago & amongst other things he tested my thyroid, FBC, ca125, took swabs & did a smear. All that was normal & he suggested it was 'hormonal' & advised leaving it a couple of months to see if it settled down.
It hasn't. I had bleeding until day 16 with my most recent period - I saw him again last week & he has referred me for a scan to check for fibroids/polyps & endometrial thickness. I expect that it'll be quite a long wait.
My next period is due tomorrow or Monday & yesterday evening I started having light bleeding & lots of cramps to assumed it was just early. More pink/red spotting this morning but it has stopped now & no sign of my period (still getting cramps). I have never had spotting before a period before. I'm planning on going back to the GP again next week to see if the scan can be hurried up, I'm really starting to fret about nasty causes of strange bleeding now :(
(I'm not pregnant or using contraception - dh had a vasectomy a couple of years ago)
