I’m sorry but pls read

If you have seen this post already it because no one has really responded to my question and I’m not getting a clear answer. This will be the last time I will post it! So I’m 13 days from my period and lately I’ve been feeling super dizzy and have stomach pain and back pain but in my upper shoulders. Me and my bf haven’t had sex since last November 2017 but we do things that don’t involve penetration...... he says that we are always safe but I always doubt that and when I get the stomach pain it just brings me so much stress and anxiety. I just need help understanding if these symptomsa are related and I need you guys ideas so pls don’t say “you posted this already” but instead give me your opinion. Thank u soo much
