Confused. Please help explain...

Hello!

Okay, so according to the test strips, I ovulated on July 9th. But this app and another app said I was supposed to ovulate on the 15th. Granted, this is my very first time using test strips to track ovulation so idk 😩

My period began Jun 27th and ended July 1st. Ovulation tests were solid on the 8th and 9th.

When I tested on the 15th out of curiosity, there were still two lines but the test line was lighter than control line. As of today, I have very tender breasts and my breast are starting to feel heavy. Hubby suspects I may be pregnant but I’ve tested all last week and this morning and it’s a negative. I think it’s still too soon to tell. Next pd is due in 7-8 days. I’ve always been irregular and somewhat started getting on track the last 4 months so I think around 7 days, I should get my pd if I’m not pregnant.

Can you ladies help make sense of the ovulation thing... like how soon after your pd are you supposed to ovulate...and if there may be a chance I’m pregnant? Thank you.
