I had a bleed at about 33 weeks and when I went into hospital they told me it was because my platelets were low but I'm not sure if that is right or if that is why I started bleeding as I also had placenta previa and had a bleed prior to the one at 33 weeks and also one at 34 weeks which led to an emergency c-section. I have a feeling the bleeding was related to pp and not the low platelets but can't be sure because the hospital never really specified. Sorry, thats probably not much help. like Kaz suggested maybe go to the GP and ask them to explain it to you.

I find sometimes hospitals/dr's just talk and expect you to know what they are saying but that is never the case, at least with me At times I just had to say 'i dont understand what you are saying' and got them to dumb it down for me

good luck with your pregnancy, try and relax
