Bled during sex at 8 weeks & daren't try again!

So as the title states during my first trimester I spotted throughout most of it and bled quite a bit DURING sex. Since then DH and I daren't attempt it again.

I'm now 16 weeks and all looks ok in my pregnancy but I guess we are both getting a little 'frustrated' and fed up resorting to just the other measures!

Anybody else been in this position that can offer advice??
