Surprise period less than 2 weeks after the last one started

[Used2bthin]

Is this something to worry about ? Noticed my periods being close together again but hadn't realised this close. Just checked back and I started the last period on 7th December. That period ended on the 11th I think then I've started again today.

I have no advice but having the same problem. Gp has done hormone tests and full blood tests all fine and being referred to a specialist. Has it been happening frequently on and off for you?

It was an issue about a year ago so I had blood tests and internal scan which were both fine. I forgot about it to a certain extent then as it seemed to settle to around every 3 weeks. I have awful pmt so it's been difficult but I'd been thinking perhaps just the way I am now but this is so close together I'm thinking perhaps I need to go back to the GP.
Is the specialist an endocrinologist do you know or a gynaecologist ?

Just a thought but I had issues with my periods that did seem to get better after I came off anti depressants. Now back on fluoxetine and wondering if that's the cause?
