Idk what to do?

I’ve been getting very faint positive pregnancy tests for the past 3 days. I’m currently 12dpo. Idk if I should continue to wait it out, or ask my dr for a blood test. Idk if they’ll even do a blood test at this point since I haven’t missed my period yet. I feel pregnant.... sore/achy boobs, tender/sensitive nipples, constipation, food aversions, headaches, fatigue, and some mild on and off cramping. I just don’t know what to think or do, I feel so stuck right now and confused.
