Been off birth control since Dec 2016. Had a withdrawal bleed 2 weeks after then my periods went back to normal. I've always been very regular (on 28 day cycle) As I've got older my periods have gone from super heavy as a teen to having a day or two where my flow is medium then a lighter day then very light/spotting for a day or so. Usually my whole period doesn't last more than 4 days, or sometimes 3.
Last month, I had my usual "pre-af" spotting (light watery brown when I wiped) so I knew the next morning, my period would be in full swing. Sure enough, woke up the next day and I was having a light flow which turned into a medium red flow. Changed my tampon a few hours later and there wasn't very much blood on it. I had no more bleeding after that. Tiny bit of watery pink/brown when I wiped but other than that, nothing.
My period was due again today. Yesterday afternoon I started getting watery brown when I went for a wee except by the evening it had gone. Figured my period would be there in the morning anyway. Woke up with period cramps, put in a tampon, took it out a few hours later and there's only a small amount of dark brown blood on it. And now it's stopped completely, not even getting watery brown stuff.
I don't know why they've suddenly gone weird, could there be an explanation for it that maybe isn't necessarily sinister like I'm thinking? lol I tried googling but I can't find any answers to my specific problem :(
