I'm trying to conceive and had been monitoring my body temperature, my temperature range from 36.11 to 36.18 degree. is this normal?

Yes !: Variation in core body temperature is common. Activity and metabolism are influential. You may want to switch this method to a chemical, urine detection kit in which you can predict ovulation some 48 hours ahead.

Timing !: When this pain occurs with regards to you menstrual cycle is most important. Normal ovulation is rarely painful. Your gynecologist may want to do a pelvic ultrasound and perhaps a laparoscopy to rule out recurrent ovarian cysts or endometriosis.
