Examples of GW from FOPT in BSM models and WallGo: I present three examples of BSM producing GW: one from SO(10) from the breaking chain $SU(3)_C\times SU(2)_L\times SU(2)_R\times U(1)_{B-L}$ (2506.07182), another from a first-order phase transition of the inflaton coupled to a dark sector (2412.17278) and the third one from reheating through particle production. As we know, uncertainties in the fundamental parameters affect the phase transition observables. I will present how predictions drastically change in these scenarios taking into account these uncertainties. I will present some results using WallGo and the limitations we have found using it..
