On Implant 4 month could I be pregnant

I'm 18 years old

-I do have frequent unprotected sex with my boyfriend.

-gaining a couple pounds not much tho

-every once in a while I feel like I'm going to be sick but idk if it's in my head or not

-skin clearing up but I'm thinking that's cause I didn't get my period this month

-didn't get period 2 weeks late

-bottom of belly feels bloated like I'm going to get period but it's been like this for weeks now

-boobs are getting slightly fuller
