back and abdominal pain

Hello po Mommies and future moms, im pregnant of our first baby na hinintay namin for more than 10 years. Ask ko lang po if normal lang sa 12 weeks pregnant ung masakit ang puson (mild pain) and back pain pero di po naalis mag 2 days na po ito and feeling ko mas mejo tumigas puson ko. No discharge naman po and spotting. Thank you po sa sasagot.
