I have read that I have a bad placement for having children and may never be able to.
I am finally at a stage where I'd love to have children with my partner, so I would love to understand that better. I also welcome any other thoughts.
Reading based on placidus house system ...
Nobody really knows - what your personal life plan in truth is really about. But actual transits show- that your idea and thoughts about having children are not coming "out of the blue".
Your venus rules your 5th house - house of own children - natally acting in reception and degree exact semisextiling your taurus mars - each in the sign of the other.
Your venus and your mars are both degree exact activated now by transit-uranus as your 9th house ruler - among others- having faith in a higher, protecting and leading power/energy above you - able to intervene- suddenly and unexpected.
With intercepted scorpio in your 5th house and a strong placed pluto in scorpio semisquaring your moon as your asc ruler and your personal birth energy and enforcement ruler and pluto zero degree exact sextiling your neptune as your life-path ruler - you have a very strong and persisting energy and subconsciously guided strong will to get your wish to have a child -fullfilled - if the right due time has come for it - this is what all planets in scorpio instinctively know - the right time.
And saturn, as your 8th house ruler - leaving descendants in own life is also transit-activated and energized by transit-jupiter's square - as ruler of your 6th house- "to work on" to get it realized.
But before delivering a child to birth, you first have to get pregnant -shown with 4th house. And ruler of 4th house first has to be transit-activated by a slowmoving transit planet - like jupiter, saturn, uranus, pluto and neptune.
Mercury rules your 4th house - the female receptive house - pregnancy and being a mother yourself. And your mercury is right now transit-activated by transit saturn as your 8th house ruler being in your 8th house now - by supporting sextile until beg. January 2022.
But there is a little difficulty - not easy to predict - your mercury is very tight conjuncting your sun - is cazimi.
