In Carols Rushman's Book 'The Art of Predictive Astrology, she states that Saturn transiting the 5th can indicate success in weight-loss. Saturn is in your 5th.
actually I lost weight when T Saturn went over Asc first house and then again T 6th house....

Unfortunately, there is no set formula or signature for marriage or childbirth, although others may disagree, apparently horary and vedic seem confident in this area. There are indicators and potential as there would be with natal, solar return chart but guarantees --

I think it's worth bearing in mind that the natal chart, like solar returns is all about 'potential' but as we all know we don't always fulfil that potential do we.
It's like someone saying you can predict death, but with modern medicine and sciences the way they are and the potential to 'die' three times in a life, doesn't mean to say you will does it

From a fellow Natal Saturn in the 5th and just finished my Saturn return, I also have Uranus in the 7th. We have a lot of similar aspects and placements.
I think I started thinking about having children when Saturn entered my 5th, but I didnt start trying to conceive until I had my Saturn return and then unfortunately it was a never ending quest of tests, etc which didnt work and hasnt worked.
Saturn in the 5th also didnt make me loose any weight, its slowly piled on since then.
The good thing, I did meet someone when I had my Saturn return and when transit Uranus trined my Uranus in the 7th. Do you have a partner at the moment? If you dont I think you may meet someone very soon. T Uranus is coming up to trine your natal Uranus and T Saturn will sextile from the 5th.
I wonder if history will repeat itself for you
Wow I have just noticed we share a birth location and a sun conjunction
