I'm 36 and we are currently trying for our third child. When I say trying, we're much more "not preventing", as opposed to actively trying. I've been off the pill for well over a year now.
My cycles used to always be 28 days, give or take a day. The month before last, my cycle was 21 days, last month, it was 27 days but I was spotting for about 6 days before my actual period arrived. This month, I started spotting from day 17. There's obviously a chance I could be pregnant, but falling pregnant for me doesn't happen very easily so I'm pretty sure it's not that.
Has anyone else had this? I'm up to date with my smear tests, I'm not on any medication. I may go to the doctors, but I do recall having months like this when I was trying for my first child, and it just ended up correcting itself in the end.
