5 days late..

Melissa • Hi my name is Melissa. I`m 20 and my boyfriend Cody is 23. TTC rainbow baby after miscarriage in July. Baby Dust everyone♡
So I'm 5 days late.. no sign of period or anything.. negative test strips the past couple of days. Should my hcg levels be built up high enough now? I only have slight pelvic pains and a sore back every now and then or I feel sick at some points.. Just don't know!
