Pregnancy Symptoms?

Ok so. I was in BC for about 9 months. I stopped over a month ago. I had my period July 1-3. We had sex the 3,4,5. (And even further back after stopping the BC)And ever since about the 6th,7th I've felt super tired, my whole body hurts, my breast are super veiny as well I'm noticing some veins in my legs. I've been a little gassy, I don't ever feel like eating but my stomach will rumble and I know I need to eat so I do but after 3-4 bites I'm stuffed, because I constantly feel full to begin with. I've had headaches and kinda congested feeling and a runny nose. Could I be pregnant? I feel it's too early to test.
