Does preseed cause MC?

My husband and I were TTC for 3 months (with OPKs) and got a negative every month. On month 4, we used preseed every time we would BD and finally got a positive at 12 DPO. But, I had to have a D&C; at 5 weeks because it wasn't a viable pregnancy. I have read SO many great stories about preseed, but have also heard a few stories saying it causes MC. I asked my OB about preseed and explained what it was (he said he's never heard of it) but that there is no way a fertility safe lube would cause a MC. We are TTC again and I'm not sure if we should use preseed or not?
