Pregnant Before Our Wedding, Advice?

(Sorry for it being so long ahead of time)

So, I found out I’m pregnant and the baby is due in early March of next year. Our wedding is not till November of next year, which I feel is still doable.

My fiancé and I were already planning a small wedding in San Francisco’s City Hall so we are not concerned about money on that end. We are paying a little extra to have an hour at city hall to be able to include grooms and bridesmaids.

We will obviously have the baby by November of next year and he or she will be around 9 months by then.

The problem is not that we won’t be able to have the wedding (we definitely can) but with our families.

Since we would be having a baby out of marriage, my family and I personally, would love it if I was married before the baby arrived. My family is very traditional. They are okay with the baby but not with my marriage status (or lack of). I personally agree with them and would love to be married to my fiancé before than and still have our ceremony wedding next year as planned.

So my fiancé respects my decision and he is willing to get married before our ceremony wedding. We are planning to just go to the courthouse in state since San Fran is out of state for us. We wanted it to just be us when we get married this way so we don’t have to have a dinner and cater to guests twice. So in a way we can still retain the glitz and glam of our ceremony wedding for our guests next year as planned.

HOWEVER, my fiancé's family is very much against this idea, especially his mother. Once we told her our plan, she immediately (and understandably) started to feel like we were leaving the family out of our wedding. I tried to reassure her that we are not excluding family from our courthouse wedding to be mean but would like our guests to see us all glamorous on our wedding ceremony as planned next year.

She still did not like that idea and has been trying to get us to elope here the same we are planning to elope in San Fran. She wants to throw a celebration with family and go to a venue instead of the courthouse. I told her that I didn’t want family coming to our courthouse elopement and she said she would be the only one who goes, but if she goes I feel bad about my own mother not going. However, my own mother would rather see me in our original planned wedding which I agree as well.

I don’t know what to do. His mother very much wants us to do a formal type ceremony here but we can’t afford that while finishing planning for the other ceremony in San Francisco. I find it repetitive to have two events like that.

I know she is a mother and just doesn’t want to see such an event be brushed aside because of a baby but we will still be having our big wedding where she will be included heavily.

I am not sure what to do I’m this situation.
