Aw hun, hindi yan kasalanan mo, most miscarriages happen dahil sa chromosomal issues na walang control ang mama, kaya please stop blaming yourself, okay? A few of us here went through the same thing at ang guilt is so real, pero it wasn't our fault. Physically kaya mo nang bumalik to light activities in a week or two, pero emotional recovery ay mas matagal talaga, give yourself grace, lalo na kaya you have three kids na umaasa sa'yo. Best talaga na consult with your doctor about when you're cleared to go back to work full capacity, because every person heals differently, at he/she can check if may complications din from the procedure. Hugs sa'yo, this is such a heavy thing to carry, but you will get through this.
