Uy mama, I can feel how scared ka right now, pero the good news is you're already in good hands at the hospital, and most importantly, you have an OB appointment bukas pa lang. Please don't worry too much until you talk to your OB directly, kasi sila lang ang makakasagot ng tama sa dating question mo, sometimes ang dating ng pregnancy ay talaga namang off sa LMP, and your OB will check everything properly. For now, rest as much as you can, and if the spotting gets heavy or you feel anything else alarming, go back to the ER agad, wag maghintay. A few of us moms have been through dating confusion too, and it turned out fine when the OB did a full check-up. Praying with you, and I hope bukas comes with really good news.
