Scared,excited, so sleepy

So I had my first pregnancy in august and miscarried in October it was a total surprise because I have PCOS and we were sure I would need fertility meds to get pregnant which I was set to start in January this year. I did start metformin in January and got back on progesterone to regulate my periods and my husband and I have been trying but I’m so traumatized by the fear of not being pregnant or worse being pregnant and miscarrying again. Fast forward to now I ovulated about a week and a half ago my period isn’t due for about another week however I’m having the exact same symptoms that made me take a pregnancy test last time. Severe fatigue, insomnia, sensitive to certain smells, irritable. But I’m scared to hope and I’m scared to test when it’s time too part of me wants to wait a month of 2 to get out of of past that danger zone but another part of me feels like that would be torture and my husband agrees. If my period is late and I do need to test the soonest best day is the day that my husband and in-laws are leaving for a week long cruise and I’m not sure if I should put off testing until we come back ( scared that it will drive me crazy the whole time wondering and worrying if I am or not) or if I should take a test morning of the cruise but if it’s negative there’s a big chance that I’ll be pretty depressed about it and I don’t want to ruin everyone’s vacation. Are these feelings normal? Am I over thinking and letting myself hope too much? I mean it could just be the metformin and progesterone combination that are causing the symptoms but I swear they are just like the last time so it’s weird.
