Sorry that you have been going through such a hard time.
Pluto retrograde in Capricorn, which is less than a degree away from the aspect (conjunction to your MC, etc. ), has brought this situation into play. With the outermost planets, you don't need exact aspects by transit to bring on an event or situation. Pluto goes direct around September 10th. Between about September 10th and 17th, Mars in Cancer will be squaring your Aries first house Mercury and Chiron conjunction from your Cancer 4th house. As Chiron is involved in the 1st with the transit if Mars in the 4th, there may be a sense of woundedness, and a physical or surgical situation that involves motherhood (4th and Cancer).
The Moon will be in Cancer between around September 12th and 14th to emphasize this. . Lilith and the transiting North Node in Capricorn will be conjunct your North Node. Neptune and Chiron in Aquarius have been squaring your 8th House Moon in Scorpio on and off, and I am looking at Chiron in particular, as it is in tight aspect. (It's true that you also have Lilith in the 8th.) Again, Chiron to the Moon in Scorpio in the 8th shows a physical or possibly surgical situation involving motherhood. This may or may not mean that you actually make a decision, but there may be a problem in continuing the pregnancy. These are the kinds of aspects you would see in the charts of people who either end their pregnancies or run into difficulties. However, you can always decide to overcome adversity and try to continue the pregancy. There is always a chance that you could do so, although the aspects do not look good for pregancy by mid September.
This is a difficult thing to discuss. I am not going to give you advice one way or the other on this, but your chart seems to indicate that you may not go through with the pregnancy. If so, that's your decision. I'm not looking at your boyfriend's chart at this time, but perhaps I will when I have time. I believe this situation is about you, and his involvement is not as important.
And some day when you decide you want to have a healthy pregnancy regardless of whether or not you have your partner's support, then you may go ahead and have one. It looks like this one depended too much on what your thought your partner wanted, and not enough on what you really wanted. Then it turned out that he didn't even want to have a child at this time. NExt time you need to know that this is something that YOU really want.
Saturn in Virgo is already moving into a square with your Venus and M ars conjunction in Gemini, and Uranus retrograde (Phase Two) will soon move into a square from the Pisces side. I think that the boyfriend has already let you down, and presently does not feel like a partner. That's the Saturn square. The Uranus square may or may ot bring a breakup, but the previous Saturn square combined with the present square from Pluto to your DC seems to already indicate that the partnership is fizzling out.
Saturn conjunct the DC in October may confirm your next move, and although it is on the DC, it may not be about partnership in the long run. It may be more about YOU. You may need to partner with yourself, and with your OWN life.
