Possibility of pregnancy after one month of stopping birth control pills

mom*may’18#😍

I will give some info which might help!

July 12 - I stopped my pills

July 19- I got my withdrawal bleeding ( lasted 4 days)

August 5 - I got a random bleeding out of the blue which lasted 2 hours.

August 14th - unprotected sex ; finished inside. ( Was constantly having unprotected sex throughout the month but only came inside once on 14th)

August 24( today) - tested beta HCG blood test which came negative ( but I feel it was too early to test this!

Since I was off the pills, I don't know when the ovulation happened and if the test showed negative because it's too early.

I am still feeling doubtful about pregnancy is because of the symptoms I am feeling. I got dizziness, stomach cramps, nausea. I don't know if it's coz of stopping the pills or if I am pregnant.
