Took us a bot over 18 months or so to get a sucessful pregnancy. I'm 12 (almost 13) weeks along now. The on again.off again birth control method did NOT work for us. For us it took provera, clomid, misscarriage, hsg test, vitamins, and then TONS of prayer for it to work for us. Seriously, you don't know how many people prayed for this!
Hope it works out for you hun! Keep trying and start looking upwards for answers.
