did I test too early? are my symptoms possible pregnancy?

Mackenzie
This is our first month trying for our first and AF due 2/3.  We didn't chart much or use opks but I've felt some weird twitching in my abdominal area last week and over the weekend I've been slightly nauseous.. but I did just get sick so I don't want to over think! I took a test today and it was negative but do you think I just tested too early? Still have 4 days til a possible missed period.  Of course I googled my symptoms and it said that abdominal flutters could occur the week after ovulation early in pregnancy, obviously nausea, and even said that getting pregnant can cause you to get sick because your body is focused on making a baby instead of fighting a cold.  Am I overthinking?
