Mandi, I haven't seen any of your posts before this one but if what Kristen says is true, then I have to agree. You are TOO young to start a family with an alcoholic when there are SO MANY good, Christian men out there who are looking for women to marry and have children with. Please reconsider. You can find a church in your area and see the available unmarried, Christian men that WILL be good to you AND your children. It is just as easy to fall in love with a good man that isn't alcoholic and THEN have children.
As to your question of having miscarriages, I have had miscarriages early in my marriage, but successfully carried a baby to full term. I did not need any type of kit to tell me about ovulation, etc. Perhaps your husband's sperm count is low because he drinks so much or perhaps the Lord is trying to tell you something, but I suggest you rethink the situation.
30 is young. You have plenty of time to make and carry babies. Many people are not even getting married until they are in their 30's, so don't let that make you feel rushed. You have time. make sure the situation is right. In answer to the last thing that you asked, my father always said "to let nature take its course" and I agree. Good Luck and may God bless you!
