Hello, just wondering if anyone has had this and can shed some light? GPS, nurses and midwives are a bit hush hush about it. I'm currently 31 weeks pregnant with my second. At my 12 week bloods my hgb levels were 12.4. I've just found out that my 28 week bloods hgb levels had risen to 17.2. This is really quite high and I'm petrified. They've had me in today repeat the test and I won't get the results till Wednesday. I've read up it can cause some horrible complications so if anyone out there has been through this I'd appreciate it if you could share your story. It seems quite a rare occurrence. Other than that result I'm perfectly healthy. Thank you. Leesha
