Question : Does this test, taken today, look like it has turned negative from the other days test (pic that was shown previously)?

Brief Answer:
Normal

Detailed Answer:
hello and welcome to a health care magic forum. the test comes positive due to LH surge after which ovulation occurs after 36 hrs . so test becomes negetive after ovulation as the LH surge decreases. This is the reason of the negetive subsequent test done today. Regards Dr Manisha Jain.

so in your opinion , you feel that I have a negative test result today, meaning that I have most probably have ovulated?

My question is...when do you think that I had ovulated? 4 days ago the test was getting darker, then on Wednesday was when it was at its darkest in color. Do you think I had ovulated on Wednesday or Thursday of this week then? Just looking for your opinion here. I understand that results may vary.

Thank you for your help!

Brief Answer:
Ovulated on Thursday more likely

Detailed Answer:
If the test was positive on Wednesday then you must have ovulated on late Wednesday or on Thursday and in either case as the ovum stays for 24 hours at least so since you guys had Sex on Thursday there are very nice chances of pregnancy.
All the best.
