Since I found out I'm pregnant I have been afraid to have sex with my partner until I'm 12 weeks, I'm 9 weeks now and I really miss that connection, I had a miscarrage about 3 years ago and it terrifies me that it will happen again, is it safe to do it at this stage?

It's safe to have sex during pregnancy unless your doctor advises you against it. Since you had a miscarriage, you would be better served asking your doctor if this is safe for you.

Yes!!

Call your doctor to be completely sure, but as long as you take it slow there is generally no danger.

The reason you miscarried might be relevant though--a good reason to consult your doctor.
