Mama, I can feel kung gaano ka-anxious right now, at alam ko yan, first time moms like us, everything feels so big. Pero honestly, the best thing you can do now is follow through with your OB appointment on August 13 and ask her directly about the progesterone timing you just realized, she'll guide you on what to do next, walang judgment. A few of us went through similar worries early on, and what helped was just trusting our doctors and taking things one scan at a time. Fingers crossed for good news on the 13th, but if anything feels urgent before then (heavy bleeding, severe pain), don't wait, go to your OB or the ER right away. Rooting for you and your baby.
