Thick Endometrium and Positive PT

Hi po. Share ko lang experience ko. I got a positive PT last January 11. Mejo malabo ung. Line so I waited another week bago nagtry ulit. After a week, mas malinaw na sya. Nag pa check up agad ako and ultrasound. Same sa findings ng sayo, no sac no yolk kundi thick endometrium. Sabi ni OB, too early pa raw. I was prescribed na ng mga pre natal vitamins and was advised for repeat ultrasound after 3 weeks. Pag balik ko, kiya na si baby and mau heartbeat na. 7 weeks 3 days sya nun. Now I am 24 weeks pregnant. It is best to get second opinion.
