My partner (F25) is overweight (F25) and I (M24)

I am planning on proposing this weekend! I have the ring and have chosen somewhere to propose. Before you ask, I have decided to propose a little before Christmas so she can tell family and friends while they are still around and she can enter the new year with the news of her engagement.<br><br><br><br>I am a little worried. You see, I have been with my girlfriend for a little under six years. In that time she has lost a little weight (around 10kgs), but this was only a short term change. She is a little overweight and I am a little concerned that this will affect her ability to become pregnant.<br><br><br><br>My concern with proposing is that I am worried she will feel let down a little if she can't have a child. We spoke about this long ago. We both want children, and I am not sure if she will feel like she is letting me down if she can't become pregnant. This is part of why I am doing it so early- if she can't become pregnant, I feel like a wedding planning process could be a bit stressful, and she might feel like she is attacking me for wanting a child. I am not totally sure of how to approach this and would really appreciate some thoughts.<br><br><br><br>EDIT: I am not where I can respond to the comments yet. I will be replying to as many as I can when I can. Thank you for the many responses so far. I am really touched by how many people are responding.
