Trying not to think too much into my symptoms

I am trying not to think too much into my symptoms this month but it's easier said that done as they have been so noticeable!
For the last 5 days I have been feeling extremely sick, also I've been having mild cramps on my left side & a slight ache on my lower back. I had a break out of acne around 4 days ago & some again yesterday. 
On the 26th I felt sick to the point I did not want to eat & had excruciating pain in my stomach. Yesterday I started to feel better but my boobs began to ache & are swollen.  Glow says I'm only 2 DPO but this is the worst I've felt since I came off BC in November 2016. Definitely feels like my AF is going to come a fortnight early. 
Anyone else felt like this & what made you feel like this?
