Hello lizzie sorry about your miscarriage, I don't no the actual changes but I do no after one miscarriage your chances of having another healthy pregnancy are very good, your much more likely to have a successful pregnancy than a miscarriage. I understand that fear though, I felt the same after my first miscarriage but I went on to get pregnant with a healthy pregnancy less than 3 months later, he's 2 in a couple of months. Hopefully your partner will come round after the shock has worn off 
bonbon welcome also, and sorry for your losses. I hope you find lots of support here, I no I do 
I'm waiting to have another attempt at the smear with the GP, who's male, doesn't bother me when it's a specialist doctor but I just imagine a male GP probably doesn't do many smear tests or internal examinations so I'm even more nervous!
Thanks everyone for the kind words yesterday, hope everyone is well
