Oh honey - my heart goes out to you. Its just rotten and I can picture myself sat there in floods of tears as some doctor tells me "Its either an early miscarriage or an ectopic" Devastating. However, at least you are getting pregnant, you are catching and I keep getting told that its a positive thing that you are able to catch in the first place. Now just getting that bean to stick. After 2 miscarriages and an ectopic, you could push your GP to refer you for tests. Please don't jump to thinking you are going to defintely struggle to keep that baby in your tummy though because there are lots of ladies on here who have had early mcs and are now having successful pregnancies. What you would expect in the first instance is some general fertility blood tests to be done. Your GP can start them off even before you get to a fertility doctor. You could have your day 1-3 bloods done where they check all your general female hormone levels (mine were done on day 1 of my cycle) then you would have day 21 bloods done which measures your progesterone (that one is to check you are ovulating which we would assume that generally you are as you are falling pg)Are your cycles regular or long?After I had those tests, at the clinic I went through the following.Polycystic ovary profile blood tests and a scan of my ovaries which confirmed I had PCOSThyroid function testLupus anticoagulant blood test - Miscarriages may be more prevalent in ladies with a lupus anticoagulant, so if this one came up positive then you normally get prescribed aspirin. Mine were negative but I was prescribed aspirin every other day anyone. (obviously never self medicate)Then I had an HSG where a dye was flushed through my uterus and tubes to make sure they weren't blocked. IT also gave a good more detailed look at the uterus lining then a normal ultrasound could give.And thats me so far, I think these tests are pretty standard once you get going with the fertility tests.For me the outcome was PCOS (which I already knew I had) and the prescription of metformin which is suggested because PCOS ladies have a higher rate of miscarriage potentially due to their fluctuating blood sugar and insulin levels. So I have everything crossed that if I get pg again that my next bean will have a better chance of sticking.Lots of love x x
