Possible 6days pre ovulation

Hello I would really like some feedback. I'm 24 I've been off and on w/ someone for 6 years. We pretty much have always used the pull out method. However in those years I never got preggers. Maybe I wasn't ovulating each time & the swimmers just didn't make it in time.

However we've recently rekindled on the 4th of December - my cycle ended the 2nd of December

(lasts abt 7 days. started on Nov. 26 it's been coming earlier lately & carrying over in the next "designated" month.)

We used our traditional method "pull out game 💪🏾" well that brings me to this question.

Can sperm last 5-8 days and attach to the egg

Ovulation started on Dec. 10th (felt cramps, emotional, bloating, fatigue)

It's now the 14th and I've been having little abdominal discomfort, slight cramps, light pains almost as if

My period is coming on but that's impossible because it hasn't been 28 days for the next cycle. I've also been very emotional, I've cried at least 6 times between Dec. 9-13.

Mucus is very creamy, white, no spotting.

This app is telling me I should expect my period on the 24th.

However I'm very skeptical because of this DPO.

It could be gas but, I feel slight pains as if something is happening.

Could it be possible I'm preggers?
