Ay sis, I totally get your worry, ganyan din ako ng iniisip ko after my miscarriage! The thing is, pregnancy symptoms can come and go, especially in early weeks, and some of us just don't get the sore boobs thing as much or it eases up, one of my mum friends said hers disappeared at 6 weeks tapos bumalik later, so it's not always a bad sign. Since you don't have bleeding or cramping and everything seems okay otherwise, it's probably fine, pero honestly best to message your OB or call them just para mapakali ang heart mo, they can do a quick check or ultrasound if you're this worried, and it's really worth the peace of mind especially with your history. Fingers crossed for you, mama!
