Hay, totally understandable kung bakit ka worried given your history, but honestly 15 weeks pa lang kaya normal kung hindi mo pa ma-feel ang movements clearly, maraming moms dito ang nagsabi na feeling lang nila first time around ay around 18-20 weeks, especially kapag first pregnancy. Para sa peace of mind mo talaga, best approach is makipag-usap sa OB mo about what you're experiencing kasi siya lang talaga makaka-assess ng situation mo properly given everything you've been through, hindi lang movement ang tinitingnan, lahat ng factors. Sending you strength, alam ko ang heavy ng anxiety na dala nito
