The chart has significant testimony that heat is one of the problems that makes it difficult for the querant to conceive-recently, Sagittarius being on the fifth and the ruler of the fifth house is Jupiter in his detriment Virgo. Sagittarius upon the 5th house means the higher mind is playing a part in the conception process also. Is it possible the use of medication may have something to do with stiffling the efforts of the pregnancy? Also have you had a physical lately?
The energy of Mars is in the 12th house and it suggests that maybe the subconscious makeup of the male is a deterring force sometimes to you. Overpowering your persona to be able to express yourself. He making a quincunx to Neptune and Pluto from the 8th and fifth houses-the house of subconscious self undoing and a 6th house health aspect. Has your husband undergone testing or has your fiancé? Here I don't know whom you will choose. You should try conceiving when the Moon makes a trine or sextile to Uranus in the days ahead and when Venus turns direct and comes back and trines Uranus. Right now there is a square aspect involving Pluto and Uranus and I hope this post does not upset you in anyway. There are some astrologer's that would use your chart for conception but as I specifically asked "when" will you be pregnant I use the time the question became alarmingly clear in the morning,it was a startling inkling when I awoke with it on my mind asking, when will she be pregnant? I prayed about it and although I don't personally know you and most astrologers use a familiarity when asking a question-(but I find you may also be able to discern by asking a question of the moment even if you aren't personally involved with the querant.) I asked the question. As an astrologer I don't and won't intrude on your life, and don't know anything about you, the only link I have with you is the original question and reply and a wish you will have your dreams under the right circumstances. A different picture altogether in most respects in some astrologers minds is this needful type of familiarity, but should you ask in a universal context there are times much light can be shed on a specific cause. I hope even if the chart is not considered in this forum that you are able to have someone whom might comment with some evaluation on the probability with the other chart. (Tikana has told you in 5 units. which could be five days or weeks or months) I see three weeks coming ahead as the timing and an opportunity even after that. Dear do please be careful because you look very young.At any rate I am hoping you will be fulfilled and have the child you wish for in the future.
All the best
