Placenta Previa

Last Saturday, my partner and I decided to have an ultrasound to check if our baby is okay. We usually have our pre-natal check up here at Dasma Cavite but since we are not satisfied with the way they check, my partner asked me if it is okay to look for another OB GYNE to check us up. And bec we were in Angono that time, nagpacheck-up na kami sa nearest lying in clinic dun. And nalungkot kami kasi sa kagustuhan namin na makita si baby on its 11 weeks and 3 days ( pero buti na lang, nalaman agad namin). May 2 findings ang doctor and I dunno if they are normal. They do 2 kinds of ultrasound to double check my situation- abdominal and transvi ultrasound. Sa abdominal ult. they saw that I have myoma pero maliit lang, normal daw na nalaki yun pag buntis and naliit din pagkapanganak.. naliit lang pero di sinabing mawawala. On my very first ultrasound, wala silang nakitang kahit ano... healthy nga daw ang matres ko so nagtataka ako.. when did my myoma started. ? 2nd findings, I have placenta previa.. marginal, inches away from the cervix. Kaya sa transvi, hindi masyadong nakita si baby kasi nakaharang yung inunan. That means, ang inunan ay nasa baba.. Today 12 weeks na si baby, sabi ni doc.. naikot pa naman ang inunan to its normal position.. I dunno if normal ba na sa gantong week e nasa baba ang inunan talaga. masyado pa kasing maaga.. but pwede daw ako duguin anytime. Pero as a mother, natatakot ako baka di na umikot.. please give me an advice. I really need to be positive with having the myoma and placenta previa. Normal lang ba magkamyoma? (don't have much info with myoma) need ko ba ipatanggal yun after? and normal lang ba ang placenta previa sa first trimester? Thank you in advance.
