Ending pill issues

Kylie
Hi ladies! So I stopped taking the pill and (tomorrow) will make 2 weeks. I know I'm not pregnant and that it's way too early for pregnancy symptoms even if I was but I was wondering if anyone of you had your body freak out since ending it? My breasts feel incredibly heavy. Not sore, just so heavy and a little back pain. I'm not due for my period until the 28th so just wondering if my body is trying to adjust and if anyone has experienced the same thing. Thanks so much! :)
