My sister in law got pregnant because she didn't get her shot on time. It's always safe to test again, I personally didn't get most those symptoms until later. My only symptoms were vivid dreams and bloating. My boobs got sore soon after. Nausea and 6 weeks but I didn't have too strong of any symptom. Sometimes we over think things though. Take a test, and try not to over think. If you're really worried see a doctor and get a blood test done. Let us know what happens!
