anxious for my period

Mianna
I met this really amazing guy. We've only been together about a month but we are inseperable. the first week we met, I had my period so we didn't have sex. The second week, I started my birth control pill and we had sex with and without condoms. He never came inside of me but I am not naive enough to believe zero sperm/seamen can get inside with just the pull out method. 
Now I've been working out, trying to eat better but due to my new boos lifestyle I've eaten more rice & beans than I ever have. My stomach has been off for two weeks. Random aches and pains here and there and semi constipation. As in, I'm not going as much or as often as I am used to. 
During the times we had sex without a condom (and he pulled out, never came inside of me) my chance of pregnancy according to this app was only 7%.
I'm venting, ranting, and looking for words of encouragement at this time. According to my pill pack, I have a week & a half until my sugar pills that bring my period. 
Has anyone been in this situation and ended up pregnant? I did take a test but I know it's far too early to detect anything. I've been taking the pill as I should everyday for the past week and a half. If I am, will it hurt the baby?
