Need some opinions. Period 12 days late

Hey there. So my period is officially 12 days late today (ughh!!!). I’m very anxious over being pregnant. My husband and I are very careful. We use protection (condoms & spermicidal lubricant). Just aren’t ready for that right now as we travel with his work and it would just be a lot. I know some are going to comment saying I need to get on birth control. I am considering it when my insurance begins again, but I’ve always had bad experiences with extra hormones. Anyway. My period was due Jan 12th. I took a test on Thursday the 17th. Negative, first response. Then I took a Clearblue digital that says you can use it to test with even 5 days before a missed period, I took the digital on the 19th. So that was negative as well. I don’t feel my period coming in the slightest. I just don’t know what to do at this point. I’m so anxious. I’ll post my results in the comments. Should I go for a blood test to rule it out? I don’t have insurance at the moment either. Stuck between a rock and hard place.
