Hiyer,
You are just like me. I have been perpetually freaked out by my periods in the last few years and am quite a few years into peri now. I never know, like you, what is right what is wrong, what is worrying, what isn't. Its like all the 'rules' you were taught are thrown out of the window. I have had a period just like the one you describe, in my diary listed as November last year lol I have said on here many times, that I had no idea that when they said 'any bleeding pattern is possible', there were so many possibilities of changing variables. Mostly heavy and small clotting, but some can be quite a bit better than others (but still very much in the heavy range).
I just wanted you to not feel so alone with your thoughts and worries. My cycles have ranged from 18 days to 40 days, some stop start, sometimes 'two a month' (but not sure it is two actually, but instead one long one). Last month my period started on day 22 and lasted 17 days, this month on day 29 of the cycle I had a few spots....and now I guess I don't know if that was mid-cycle hormonal change or I've skipped over one. Seeing as I've had more 40 day cycles recently, I'm guessing it might still be about to come. Sometimes, like you, I feel accepting and just able to say 'so its just natural changes, its going to happen' and many other times I feel very anxious about it. Does it seem to you that just as youo get used to one change another comes along the next month ? LOL Its unsettling, I understand.
If you want to message me and talk about our shared experiences I'm really happy to listen..and errr....share. I can't offer advice, like these other seasoned meno graduates.....but you aren't alone with confusion, frustration and worry.
