Hi sis, ang feeling ng buntis talaga ay different from person to person, iba-iba! One of my mum friends had zero morning sickness pero grumpy lang siya nang two weeks straight, while another felt nothing at all until month three pa lang kaya huwag mag-worry kung walang classic symptoms. Since delayed ka na ng 2 months and may physical changes ka (bloating, that tight feeling, early fullness) kahit negative pa ang PT, mas better talaga na makita mo ng doctor para ma-rule out kung ano talaga ang nangyayari, pwedeng blood test or ultrasound na lang para alam mo for sure, kasi sometimes PT ay late pa or may other reasons din for delay. A few of us from our mommy group went through something similar and ang peace of mind from checking with OB ay priceless talaga, so don't wait na!
