Advice please

I’ve just found out I’m pregnant. I am OVER THE MOON. Completely unexpected (unexplained fertility issues) I do however have a little dilemma I’m hoping you ladies can give me your honest advice.

I’m due to go away with two girlfriends next week to Ibiza. I can’t cancel without explaining why but I’m not prepared to tell them I’m pregnant before I tell my mum and I want to wait untill I’m in the safe zone of 12 weeks before I get my families hopes up etc. The girls

won’t go without me as I’m the common friend between them. They have paid for flights/hotels/tickets so I’m going to feel absolutely awful for them to lose all of this.

I’m considering still going, they won’t notice im not drinking as I’m not a huge drinker but my main worry is the noise in the clubs? Could the very loud noise level harm the baby at this early stage. I will not take any risks to the baby what so ever I’m just not sure if I’m over worrying about noise levels.

Sorry this is long. Any advice greatly appreciated.
