BBT keeps going up, a good sign!?!?

Megan • Happily married. One 2015 angel baby, little girl born Sept 2016, & one due June 2019.
So my BBT keeps going up. Took clomid CD5-9. I took an opk this morning with FMU since I've heard they could sometimes detect early pregnancy. It was positive. I'm waiting to take an actual hpt until Saturday. So nervous!!
