I am 16 days late now and I took a hpt test this morning and it came back negative. I have not been feeling like I have the flu or anything, so why have I vomited 6 time in 16 days, nausea, bloated, late, cramps, lower back ache, head ache. My nipples hurt and are very sensitive, the last time they were both this sensitive I was pregnant. Please help I am so confused.

Even at 16 days, home tests can have false negative. Some women do not correctly test till they are 4 to 6 week late.

You can either wait, or go for a blood test at doctor.

At 16 days late, it is slightly early for those "signs"
