3rd pregnancy

Hi mummies! Just got to know i’m pregnant for the 3rd time. Was having mixed feelings at first when i saw the results on the kit and immediately cried. Reason is because i wasn’t ready and overwhelmed because my daughter is only 2 years old rn. I’m afraid i can’t give equal amount of love to both my babies. Secondly, my first son passed on bcs of a disease and i don’t want the same thing to happen. However, my husband was so happy to know that i’m pregnant and he kept being positive about it and now my views change and i’m starting to accept this pregnancy. Please pray for my mental health. Aside from this - may i know what folic acid can i take OTC watsons/guardian? Cause i’m still waiting for my polyclinic referral.
