Answers please!! Too early for symptoms? Help 😭😷

My lower back aches so badly it's making me sick. Which would just add to the extreme nausea that I'm feeling. Ive also had a hard time breathing and (tmi) very very white creamy cm. I have an awful headache and my emotions are crazy all over the place. I've cried so much today. And holy tiredness! Help??😭

I had sex two weeks ago. Do you think I could be pregnant? Could I be feeling pregnancy symptoms already? My period in 10 days. Is it too early to test?
