Hi Cancerian,
I have nothing much to add in terms of medical astrology, per se, but I am in agreement with what other members have said about 'trying' to have children.
Looking at your natal chart, you not only have have the Scorpionic/Plutonic qualities that other people mention, but your chart is a map of power struggles, probably from childhood, which you now probably internalize. You have a Moon/Pluto conjunction squaring your Sun. I would venture a guess that you are often at odds with yourself, between cogent thought and emotion. People with Sun/Moon squares often try too hard to intellectualise life to the detriment of their feelings, or vice-versa. Sometimes they don't know what they're feeling; their thinking blocks it out. Your Sun is also squre Pluto, and squares are about power: who has it, who doesn't, how it's used. People, especially, with Sun/Pluto squares often experience dominant/submissive issues with partners, usually stemming from a perception in childhood of the 'Father' (or the person representing the father figure) as domineering, controlling, manipulative. Sun/Pluto square people just hate to be controlled, and often overcompensate for their feeling a lack of control, by being overly controlling with others. I know. I have this square!
The Moon/Pluto conjunction squaring your Sun is also an interesting one. Again, this is about *power*, and what this speaks of is the Mother figure (Moon/Pluto, a very powerful mother, but very manipulative) at odds with the Father figure. This may or may not be what happened in your childhood, but somewhere inside you there is an idea that 'relationship = struggle for dominance' and this dominance may not manifest in overt power struggles, but in subtle manipulations: witholding, withdrawal, non-compliance. Sometimes it is not the loudest shouter who is the most dangerous; sometimes, it is the quiet one in the corner of the room.
You have Uranus on the Ascendant. You are nothing if not independent; and I wonder, with this other stuff in your chart, whether this is a sort of bid for control over your life. Not consciously, probably, but it sounds like your husband is calling most of the shots (insisting on a biological child, refusing to foster) at the expense of what *you* want, which is to have a child, any child.
Are you genuinely happy with this arrangement? Is life *really* that perfect?
What I'm saying with all this is: while there *may* be some medical issues (has your husband had his wigglies checked, by the way, or is the fertility issue 'all yours' according to him?), I think this is more of a psychological block; and, like writer's block, when the power can't flow, there can't be a conception.
And look, twenty-four is still very young; I didn't have my first child until I was 28. A friend of mine just had her first and she's 37. You have *time*. Stop pressuring yourself, and for goodness' sake stop whatever pressure your husband is putting on you and just enjoy life. You still have a long, long time to have a child, or several. If you are having sex only at fertile times, measuring your temperature, etc.: stop. In fact, stop having sex for awhile; stop until you want it so badly you can't wait to jump into bed (or onto the kitchen table, whatever). Stop thinking about having babies for the time being; stop being so *hungry* for it. If it's always lurking in the back of your mind, you cannot be focused on
NOW and the more you try to project your life into some 'only will be fulfilled when I have a baby' future, the unhappier you will become.
Best,
AG
