Inert Doublet Model is a minimal extension of the Standard Model with the second scalar doublet that may provide a Dark Matter candidate. We consider possible evolutions of the Universe to this state during cooling down of the Universe after inflation, taking into account first order of the temperature corrections to the potential. We argue that in the past Universe could pass through phase states having no DM candidate. In the evolution via such states in addition to a possible EWSB phase transition (2-nd order) the Universe sustained one 1-st order phase transition or two phase transitions of the 2-nd order. We consider the evolution of physical parameters, taking into account the existing accelerator and astrophysical constraints. Talk is based on following works: arXiv:1009.4593 [hep-ph], arXiv:1104.3326 [hep-ph].
