I had OC with my first two. Both times it came on (the itching) around 34 weeks, diagnosed by the blood test at around 35 weeks.
This time no itching and bloods at 37 weeks came back normal.
My first was born 12 yrs ago, When the OC was diagnosed I was kept in hospital for over a week, started UDCA tablets and had blood tests every second day. Went home but still had to have bloods taken every ither day, growth scans, scans to check blood flow through the umbilical cord, placenta function etc, and then induction at 37 weeks, but the induction worked right away and had my baby within 10hrs of being induced.
With my second, nearly 10yrs ago, they did bloods every 4 weeks from about week 20, til diagnosis at 35 weeks (I had actually started itching about a week earlier but those bloods were normal, they only went abnormal several days later) and then had bloods taken twice a week after that and on the UDCA and Vit K again until I was induced at 37 weeks. Also had all the monitoring like with my first.
This time I had a consultant appointment at 16 weeks and she just said come back if I had any itching, which I haven't.
My midwife decided to do OC bloods at 37 weeks just in case but they were normal.
This time I've had no scans or dopplers, but tonnes of blood tests due to low platelets lol.
I will say that I looked it up and found a few sites saying a low fat diet and Lecithin can help so that's what I have been trying to stick to over the last 4 weeks. I bought Lecithin off amazon (Veganicity brand) and was taking 1 or 2 a day til recently but I only have 3 left so skipped today, don't really want to buy more but this baby might not come any time soon lol.
