1st time pregnant & sex (tmi) kinda

This might be tmi for some women but oh well we're all adults here .. soo me and my boyfriend always had a good sex life & of course I would give him head and I would swallow when he ejaculated well now that I'm pregnant it don't work like that anymore 😩😂 and I seem not to be able to give head for along period of time because I get EXTRA nauseous .. and I really don't think my bf understands .. I just wanna know if this happens/ happened to any of you ladys and I also tend not to experience an Orgasm but he gets his nut in about 7 mins 😤😒I mean I'm okay with it , just because I never be in the mood anymore idk ,I feel bad I don't want him thinking I'm not interested because I am but sex not everything to me .. like what is life 😩😂 or should I say sex life lol
