Made of honor went over budget!! Stress while ttc

I know its off topic but it is stressfull while ttc. Made of honor is the my friend (in which i only known almost 2 years) is her fiancé sister. We all set a budget at 140 for the shower and she them tells us after the shower via text she went over budget by $50!! I was upset bc on top of other cost it adds up i would of been fine if i was asked if extra i could afford to pay. I sent a message to the MOH explaning how i felt abd that i could not afford i just bought a house and i just cant do it! She never redponded until another group message came out few weeks later before bachelorette asking for it agin and told us she actually went over 80 each girl x 5 but he being nice shes only adking $50 how rude! Anyways i ignored bc i never got a respond and she didnt need until rehearsal or wedding day. So here we are again group message asking for it this Thursday or friday expecting we will have it on top of other things thst day in have to pay.!(hair, make up, wedding money, and hotel!) im stressed out ttc and this could mess my time ttc. I dont know what to do. Seems not alot but add everything up it is besides she went over without adking. Grr please advise. O btw i look bad bc some girls are her fiancé cousins so of course they are ok with it.
