Possible padin mommy. Same case tayo. Malabo ang line ng PT ko when I first took it. Pero I know POSITIVE yon kasi hindi nangyayari sakin yon kapag nag te-take ako before. So I was asked by my OB to do a transv, wala pang nakita. Thickened endometrium din ang findings. I waited for 2 weeks, then surprise! 7 weeks baby after another transv 🥰 She's now 7 months old hehe. Iwas stress ikaw mommy, and more more rest. Goodluck!
