Hi Hun,
Try not to worry. My periods were always a breeze, used to take the piss out my sis cos she used to cry when she had hers and I didn't know what the fuss was about.....until 6months ago. We have been trying for 14months now.
2 months ago mine were sooooo bad, i went thru 3tampons in an hour, to the point i had to put a pad on too. I was in tears, doubled over, couldn't walk and White as a sheet. My oh took me to the docs asap and I was prescribed mefenamic acid, this is for the pain itself and tranexamic acid is to slow the flow down, not stop it, just calm it down a bit.
He gave me enough to cover 2months, but I get it repeated. I take it when I first get a show and it's not too bad after that, still sore, still there etc, but a lot more bearable.
Please go to doctors and explain Hun. Let us know how u get on xx
