Always had a regular but slightly short cycle (27 days). Since TTC I have months where it's 25 up to one month at 30. The rest are my usual 27 days.
I have really light flow (mooncup day 1-2, can get away with liners from day 2 and only need 2 a day and then light spotting until day 4 & that's it). Today AF turned up again and I noticed the flow was bright red this morning when I came on, but within 12 hours it's dark red and almost brownish. (Joys of mooncups eh, suddenly have you noticing all sorts - sorry)
Do you think there's a link between really light flow and not having enough lining for implantation? It's a long shot but thought I would ask.
Sounds like you were talking about me. My cycles are very similar. Been ttc for 6 months now and asked the doctor this question and he made out like short periods weren't an issue.... I thought the same as you, surely it makes a difference?
My periods are really light (pads/ mooncup for 2 days then liner/ lightest pad and nothing at night for 3 days. I got pregnant first time trying twice. So I wouldn't say light periods in and of themselves are cause for concern.
