I need help Abortion or my vacation

I feel so sad. I’ve never experienced leaving my country and have a beautiful trip at a 5 star hotel in Mexico booked as a gift from my fiancé. Him and all of our neighbours planned this and I don’t think I’ve ever been so excited to do something. He also has travelled a lot in his life where I haven’t.

I have a 5 year old daughter (his step daughter) and finally feel a bit free to actually do things after having her young. But I’m now pregnant, it’s early but I don’t think Mexico will be fun while everyone is around me drunk in a pool and I’m alone trying to enjoy it. If I go after having the baby I won’t have the same childcare with a 7 year old and 1 year old. We’ve said we wanted another but want to live a bit of life together first. I know how much you miss your partner in the first year after having a baby because I remember.

What do I even do? I’m so sick to my stomach and just devastated. I grew up with very little money so this was just an outta this world gift to me and now I feel like it’s gone. I’d be a horrible person to abort for just a vacation. Resentful
