Scared of sex after m/c

OK it's only been a couple of days and my dh is dying to start trying again. I agree and I absolutely love him to bits and there is nothing more than I enjoy is spending time with him beneath the sheets but I am absolutely bricking it. I'm so nervous like it's my first time again but also scared that sex means possibly having to go through the suffering of another m/c. How can I get over this?? X
