Fever?

I’m 7 weeks now and I measured my oral temp and it was between 99 and 100, and then knowing that rectal temp is even more accurate I tried that and it was about 100.18.

Should I be worried that this is a fever and can harm my baby?

I think I have a cold because I have nasal congestion and horrible post nasal drip.

I know they say fever of 100.4, but are they referring to oral or rectal? Because rectal will ALWAYS be higher in anybody due to it being more in the body’s cavity.

I read some scary stuff online regarding fevers in 1st tri. Did anyone have fevers like this (low grade) and go on to have a healthy full term baby??

Any insight much appreciated thank you!
