Possibly pregnant?

Paula
Hey everyone. I'm new here but have a question. 
I am new to the pill after changing from implanon and I have a few pregnancy symptoms that could also be PMS 
My breasts hurt and feel heavy
I feel sick throughout the day
I'm tired all the time 
Mood changes
More acne 
I am due for my period in 3 days but I'm not 100% sure if it'll come. My partner and I always have unprotected sex (pill taken on time every day but no condom)
