Hallow Dear,
Pregnancy test on urine (HPT) would not be useful to ascertain or even detect ovulation. These tests are specifically meant to diagnose pregnancy.
Your BBT chart changes suggest that you have ovulated on the day when you had an ascending spike. Just before the ovulation, there is a drop by about half a degree followed by rise of one degree when ovulation takes place. Then again there is a fall by half a degree and the temperature remains that high.
You are on Clomid; i.e.
Clomiphene citrate. This medicine can cause release of more than one eggs. Hence you had two spikes of temperature rise .
However, to ascertain the evidence of ovulation,
ultrasonography is the best tool at our hands. Ovulation monitoring by USG can spot the day of ovulation. It can inform us about the number of egg released also. Apart from the visual evidence of ovulation, it provides following important relevant information:
1. Follicular size at the time of ovulation: Follicles between 18 mm and 21 mm release healthiest eggs which can result into successful pregnancies. It may facilitate the decision of
hCG injection if planned for.
2. Endometrial thickness: Uterine lining (endometrium) between 9 mm to 14 mm thickness is most conducive for the
implantation of the fertilized ovum.
I hope you will take help of USG in future rather than just relying on BBT chart.
