Pregnant or scared?

Hey ya’ll.

So I’m supposed to start my placebo pills next week. I usually withdrawal bleed between Monday - Wednesday. I’ve been on birth control since 2017, and I’m in a relationship with a wonderful man, but we can’t have a baby right now with the way our lives are going, so I’m religious about taking my pills. We also use the pullout method in addition to me taking my pill.

This week I’ve been feeling a bit strange. Having really bad cramping in my lower back mostly and feeling wetness earlier than I usually do. When I wipe though I’m super dry. However, I did get into a pretty bad car accident this week and that could have something to do with it, I’ve had pain traveling around my body.

Other than that earlier this week I felt really tired on and off, not consistently, especially when I was occupied with something, and yesterday had a sudden 5 minute or so onset of dizziness.

Are these early signs of pregnancy? I’m scared of being pregnant so, I could just be making everything worse due to anxiety. I haven’t seen any other symptoms so.
