I’m pregnant

Okay so I found out me and my boyfriend are having a baby after being with each other for a year and a half and we’re both very very excited ummm I’m only 9 weeks but my body is changing everyday I feel.. I’m a Scorpio so I love love loveeee having sex with my fine ass man but ever since I’ve been pregnant I don’t wanna have sex like that and he swears I’m not into him and it’s not even like that I don’t understand why I’m like that all of a sudden .. what should I do to spice us back up ..
