Badly need help ☹️

First time mom here. Actually, 4 positive PTs na lumabas sakin but lahat fainted. According sa pregnancy calculator 4w3d na ko. I was supposed to have a check earlier kaso kung hindi walang available o.b, sarado naman ☹️ tatakot ako kasi minsan nagccramps ako. Di ko alam ano ba dapat iinumin kong vits or what. I'm really scared to lose my baby since I just lost 1 last year, around November. Natatakot ako maulit ulit yun. What should I do? I'm really scared. Actually, unplanned to, still Im really grateful for this blessing. Yun nga lang sobrang natatakot ako. Huhu. Help!! ☹️
