Please dont judge just looking for advice

I'm pregnant with my first baby he is due on 24th April. One of my best friends have just got engaged and is getting married in July.

Shes organised a hen do for may 17th for the weekend I really want to go but it's less than a month after my baby is due. Would this be too soon to leave him? I have such mixed emotions about whether to go or not it is driving me crazy! :(
