Monistat yeast infection pregnancy

Im pretty sure I have a yeast infection and I only have Monistat 3 and I don’t really wanna use the 3 I only feel comfortable using the 7 but monistat 7 is just cream that u put in the tube and the 3 comes with cream for itching as well I was wondering if it’s the same cream and if I could just use the cream from the 3 up there and it be the same as the 7
