Taking to many plan b bad?

So ever since I started seeing this guy I’m with he’s been buying me plan b all the time and I’ve been taking them because I wouldn’t want to have a kid if he didn’t want to I’m not the type to drag a guy down with a baby and I’m not really ready and I know if I’m not ready I shouldn’t be having sex whatsoever I’ve heard it before if any case I would love a child just when it’s time and I’ve been taking up to two plan b a month and I decided not to see him anymore yesterday he bought me a plan b but I didn’t take it not because I want to get pregnant from him but because I don’t want to keep harming my body they make me sick to my stomach and my periods haven’t been regular and I get bloated I’ve GAINED weight ever since I didn’t tell him I didn’t took it because I’m scared of what he will think I’m fertile right now but I’ve seen so many girls struggle convincing and I know it takes a lot of trying but since I’ve been avoiding it I think I’ll be good or should I take it I really do want kids in the future with the right guy he’s so manipulative I tell him to use protection but he obviously doesn’t love me to even care for what I say if he doesn’t want kids either why keep coming inside me knowing I’m not on birth control I push him away but in the moment it’s not as easy all the time im starting to get really concerned about all those plan b I’ve taken about 9 this year
