Absolutely! I had 2 m/cs and had 2 healthy boys after that. Then we ttc #3 but had to have some help(meds im getting old! Lol) and had a little girl. Since it takes you so long to conceive you may want to consider seeing a fertility specialist. They can help. Good luck.
Yes, of course there is. What age are you? If you're in your 30s or 40s then as you age it does become more difficult to conceive and the quality of your eggs reduce, so conceiving can become more difficult, as well the chances of miscarriage being higher. That doesn't mean that it will never happen, just keep trying and when it's meant to work out, it will.
