I took 3 pregnancy tests that came back positive and according to my calendar and <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a>, i am 5 weeks. I dont feel anything! No sickness, no food adversions, no bleeding, no nothing! My ultrasound appt is in 2 weeks but as of now i feel nothing. Should i be worried or am i overthinking? Please offer your advice please.
