Is it too early for these symptoms?

K♥️

I have been having a ton of gas (tmi) and feeling nauseous on and off for the past 3 days. And when I eat I feel so full like I ate a huge meal. For example today I had a small homemade grilled chicken salad with cucumbers and tomatoes and I feel like I ate a huge steak dinner. So I’m feeling very full after eating not so much. I also had lower back pain yesterday after working out. And have had light dull cramps for about 3 days I am due for AF in 3-4 days. Is it too early for these symptoms? Has anyone experienced this and got a BFP? Trying to hold off on taking a test. It is just so hard. I should also add I’m 11 DPO.
