Had sex 2/22....3 times. Took ovulation test on 2/24 and it said the LH surge (I'd be ovulating) in 12-36 hours.  On 3/5 and 3/6, I felt what I thought were period cramping pains, but my period didn't come.  At 7AM on 3/7, I took a Walgreens pregnancy test and it said I was pregnant.  We have only been trying for a month.  One line was fainter than the other, but nonetheless, still pregnant.  Again, I am 37 years old and conceived naturally 10 years ago, (healthy boy) and now we're having another baby!  We are hoping for a girl this time!! This is excellent news and we are very happy!!  I wish you all luck in your journeys!!!!
