Back on BC

Hey ladies, i have a question. To make this short i was on BC for 2 years then i stopped taking it mid-pack due to personal reasons. I ended up pregnant in February had an abortion in March due to personal reasons. Now i am back on BC on my second week now & i feel terrible my breast feel sore, body aches, fatigue, & not really eating . I am not sure if my hormones are out of wack but i just feel terrible. I did have sex twice before getting back on BC but both times were protected. I’m worry that something might be wrong but then again i just think it’s my hormones should i worry?

(Also to mention when i did stop taking BC i did take Plan B due to me & my boyfriend having unprotected sex at the time) - that didn’t work out still ended up Pregnant.
