Although it is very apparent you are 'wishing' (Moon mutual reception with Uranus ruler of Aquarius, hopes & wishes on pregnancy 5th of children). Dignified Co ruler Uranus in Capricorn by mutual reception with the Moon, thoughts)
Moon now becomes Exalted in fixed Taurus in the exchange, a prized pregnancy, it is healthy as pregnancy Moon will be published in 7th of marriage partner and marriage 7th) With Fixed Aquarius on the 5th, Capricorn energies (Saturn in Aquarius), are ruled of strength, a solid dignified Saturn in another Fixed estate (Saturn rules the skeleton, teeth, bones and cartilage, Mars rules muscles).
Uranus dignified in Capricorn by mutual reception with Moon in the 3rd (the babies turned 11th house; and your husbands 9th of higher mind), - the sign of 'hopes and wishes' 5th won't necessitate any sudden unexpected event that will prove the child will be unhealthy, a normal pregnancy is most likely, but I think the term may be sooner than later. Uranus rules the 5th house.
Scorpio rising in the 'Via Combust' suggests 'things not aught to turn out well for the querent' (Lilly). Mars in Taurus mutual reception with Moon in Capricorn (Exalted states), thinking it will be a boy, but, no for twins-fixed signs on the Ascendant, 7th house speak of the husbands inheritance of physical traits. Only see a 'no' for twins as Via Combust rises on the Ascendant. Venus in Gemini does suggest twins, but does not bode exemplary reception in Mars, Pluto's 8th house. Please don't be too disappointed, should you be wishing for a girl. Gemini Venus (twin energy) the promise of twins is doubtful.
If you prepared your womb for the possibility for twin reception (fertile environment {serums that promote twins-medication etc} suited to welcome-promote the ovum and fragile sperm nesting grounds (temperatures, acid versus alkaline is taken into account}, I would say the planning would give you a better chance to have twins, but looking at Venus square Neptune does not promote that aid by medication, and the strength of Masculine-Fixed Saturn in Masculine Aquarius, Moon (ruler of pregnancy, Pluto parturition), another testimony of one ovum fertilized. Moon is in feminine (destiny 10th) Capricorn and Joys in the 3rd, (bright thoughts of hope) but does not end up where she plans, (Ivy Goldstein- Jacobson), but, is in detriment, & although in mutual reception with feminine Uranus (he is a malefic) in Taurus, the mutual reception, even by trine between the two (ease of success for the quest) is most likely doubtful. Each aid the other (Me Casa Su) to get out of their predicaments in the present sign each are in, difficult pregnancy, unexpected incidence is negated, nothing to worry about. Moon gives the lad a beautiful continence and he is healthy. The only unexpected turn about could be a question of term for parturition (Pluto in Cardinal Capricorn, Uranus in in mutual reception with Moon (exalted Taurus) he then is in dignified Capricorn, don't be alarmed if the term is less than 9th months, the quickening comes sooner than later that's all.
Please excuse the long dissertation-it is lengthy but thinking the additional information might ease any disappointment that should occur in your future hopes. Wishing you your husband & the beautiful baby boy a loverly 9 months of joy.
