Hello,
Sorry for the long post but I don't want to drip feed. Please bear with me as I am desperate for an answer.
Note: By posting here I am not questioning the consultant's decision but rather seeking to understand better my current situation and the possible treatments. I feel foolish now but at the time I felt that I took too much of the gynaecologist time over the phone telling them about my history over the past 7 months, so that when they suggested the next step of treatment and told me briefly what it was I didn't ask any other question 
I really do feel that I wasted the opportunity to ask all the questions I had, considering that I waited so long to be able to talk to a specialist...Oh well, I blame my sleepless week due to the heatwave!
I've been bleeding every single day for almost a month now, with my "periods" getting heavier and heavier culminating in flooding for the past week. Nothing seems to work.
I've always had regular seven days periods but about six/seven months ago, suddenly, out of the blue, I started haemorrhaging and it lasted for about 3 weeks. Since then my periods are very irregular, flooding (much heavier than post-partum bleeding) with at least a month and a half interval, and always flooding.
Since the problem started I was prescribed Tranexamic Acid which I find not very efficient. Has transvaginal ultrasound which found nothing amiss. Had to go to the A&E where I had a vaginal examination by a gynaecologist which again found nothing amiss and I was told I might have a Dysfunctional/ abnormal Uterine Bleeding, but had to have a proper appointment to be assessed more thoroughly. Managed at last to have a phone "consultation" with a gynaecologist who told me I needed a hysteroscopy, although when that will be possible I don't know as I am now on the waiting list and things are very slow with the current situation.
I'm 37 with two DC, 7 and 3, vaginal births. No hormonal birth control. No major change in my life. I am taking multivitamins + iron supplements after a blood test found I had low haemoglobin after my first bout of flooding. I am at my wits end and it's affecting every area of my life.
Why do I need a hysterescopy when a vaginal ultrasound and exam didn't find anything? What may be the cause? What are the alternatives to the Mirena coil? How can I manage the bleeding as nothing seems to work?
Also, I'd be really grateful if anyone who tried natural treatments (herbs, lifestyle changes, etc.) which worked could share them with me so that I could research them. I always favour natural treatments if possible but will always turn to traditional medicine when needed.
Thank you.
