Is the chart correct to read now?
Yes.
Based on just your natal chart, I'm not surprised to hear you have ongoing conflict with your mother. Your Mars is square your Moon, and your Moon itself is in volatile, short fused Aries. In the eighth house, too, which can be a very difficult house. There's a suggestion there that your mother has experienced some great conflict or tragedy, which, not necessarily intentionally, she's passed on to you. Maybe through that difficult relationship. Or maybe you've subconsciously absorbed her difficulty.
Moon also describes your family of origin, your home, and, in particular, your childhood home. Was there much conflict in your family when you were growing up? Is there now (aside from that obvious conflict between you and your mother)?
The synastry between you and your mother is softer, interestingly. Your Mars and hers form a tight sextile. That suggests a relationship involving competitive, affectionate banter. Not one upmanship, not cutting each other down, but playfully sharpening your wits against each other. Does your relationship also have that quality to it? Has it in the past, if not currently?
Your Moon and hers are sextile, too. That suggests an ability to harmoniously co-exist, and that it's not too difficult for the two of you to understand each other's emotions.
Assuming the birth time you have for her is correct, her Moon is on her ascendant, and her busiest house is her fifth, which includes her Sun. That combination, in the chart of a woman who is a mother, indicates a very, very strong identification with the mothering role. She may feel that her children are, essentially, herself.
Not only that, her whole northwest quadrant--the fourth house of home and family, the fifth house of children, and the sixth house of duties--is where the bulk of her placements are. Put all that together, and it would be all too easy for her to narrow her entire life down to focusing on her home and family, especially if society encourages that, which it often does to women with children. Has she restricted her life to that?
The takeaway I'm getting is that she sees you as an extension of herself, and she takes your weight gain personally. Is she insecure about her own weight? Moon on the ascendant can be associated with a tendency to fatness, to putting on weight, and the closer that Moon on the ascendant is to full, the more likely it is that it will show up that way. Your mother's Moon is in a waning gibbous phase: no longer full, but still closer to full than not. Does she have a tendency to put on weight? Has she perhaps struggled with it all her life?
