Wanting to try again

I had a miscarriage in February and was told to wait one cycle and I told everyone I wanted to wait two.  My close family knew n I went to my uncles as a get away right after I miscarried. My uncle is like me second dad and it was great to spend time with him n get mind off the sadness. He n everyone knew I wanted to try again soon. I just found out he is getting remarried and the wedding is a cruise wedding in January. If I want to go I have to postpone plans to try for the next 5-6 months. Is it okay to be mad and frustrated?
