You Profile says that you have been married 2 years ago. But your question says that you started intercourse 6 months ago. Was there some reason for the delay in having intercourse?
Though you may have been married for 2 years, 6 months of intercourse is not really a long time for getting pregnant. Sometimes pregnancy can happen the first time you have intercourse and sometimes it takes much longer. There is really no scientific explanation for this and it is just one of the wonders of Nature.
You need not bleed the first time you have intercourse as your hymen could be broken due to many reasons like using tampons during your periods, strenuous exercises, masturbation etc. You can read about this in our Articles posted here. Just type hymen break in the SEARCH Box on the right.

Do you still get pain during sex? If your husband indulges in sufficient foreplay and you are well lubricated then there should not be any pain in your vagina. You could try the cowgirl riding position instead of the traditional missionary position. Here he will lie on his back and you ride him, so that you can control how deep you want his penis in your vagina.
If you still do not conceive after a year of intercourse, it is advisable to see your Gynaec who will advise you the best course of action.
Stress also plays a negative part. Just enjoy sex and do not worry about pregnancy. It will happen.
