Thanks @ThePopandCry for pointing me in the right direction to this latest thread, posted the following on an old thread! 
Hi Ladies
Thought I'd introduce myself, after a couple of years of non Netmums membership and darting in and out of googling here over he last couple of years, thought I'd join up!
My husband and I married in May 2013, we started trying right away and it took us until the Dec 2013 to fall pregnant.
I've had 3 early miscarriages.
MC1 – at 6.5 weeks directly after an early transvaginal scan at EPU. I'd had 2 previous early scan to make sure that a small amount of ovary pain I'd experienced wasn't an ectopic. The 3rd scan at EPU took well over 10 mins, a trainee and a fully qualified sonographer scanned me. The trainee didn't hurt me at all, but when the fully qualified sonographer took over she was digging around and caused me a lot of pain. They eventually found an empty yolk sac at the top of my uterus. I literally got off the scanning bed and walked out the door of the unit and it started. Then it started proper Xmas Day 2013, had a minor car crash on the way to the local hospital and miscarried proper there.
MC2 - Missed miscarriage at 12 week scan, Oct 13th 2014, (13 NOT my lucky number either!!) although I had suffered spotting from 7 weeks and asked the doctors and A&E for reassurance as I just knew something was not right and had persistent left shoulder blade pain, I was told to hang on for 12 week scan and was told there that it hadn't progressed beyond 7 weeks.
MC3 - Mid Feb 2015 at 4 weeks and 3 days. All of the miscarriages managed naturally, although no.2 resulted in contractions and awful bleeding on a car journey home and managed at a wonderful local urgent care centre. Went in to a bit of shock in the early hours later at home and was looked after and monitored by wonderful ambulance crew at home.
I've had the full gamut of blood tests twice as the first ones were lost. All are normal.
I decided after MC3 to go for the uNK cells test at Professor Quenby's clinic in Coventry.
I've just had my results from Professor Quenby and I have 7.4% uterine Natural Killer Cells. 5% is what they would call the upper limit of normal.
I started on the Progesterone on CD21 came off CD28, started spotting on day 31, period started proper on day 33. I am normally as regular as clockwork 28 day cycle most of my life. My period this month is very blood red and very heavy this month, not like normal at all with a bit of abdominal and under rib pain.
Can I ask has anyone else suffered this after taking Progesterone (cyclogest)?
Also if you've been diagnosed with high uNK cells at Professor Quenby's clinic what was your percentage count?
Thanks in advance.
