I don't know if I am pregnant or not (LOT of negatives tests, blood test negative and then 2 positives hpt)

I will see my doctor next week.

I am nauseous, throwing up every morning, dizzy, tired

My friend told me that the body temperature could be a sign? I need advice please :)

3/19 night: 98.9

3/20 morning: 97.4

3/20 night: 97.8

3/21 morning: 98.4

3/21 night: 98.4

3/22 morning: 98.8

3/22 1 p.m.: 100.0

And these are the 2 lasts negatives before the positives... they really are negative right?

Thank you!! :)
