Relationship/Sex

My boyfriend and i had a point in our relationship where we had sex everyday ..now that i don’t want it it’s a problem between us! I have my times when i want sex so much it’s like an addiction i have to have it either myself or my man but then i have these moments when i don’t want it at all and go months without it! How do i get him to adjust to that or should i just sex him when he want it ? Not to mention he’s been trying to get me pregnant since we first had sex my cycle suppose to come on today but I’m having no symptoms of a period ..I’ve only been nauseated and just feeling like BLAH (been this way for a couple days) so that’s another reason we haven’t had sex in like three days ..what should i do ?
