Pregnant??!

I have a regular cycle that lasts between 27-29 days each month. Came off the birth control pill in November last year. I just recently finished my most recent period..... started 16th February and ended 22nd February. (Currently 13dpo).

The last couple of days I have been feeling so yucky!!

Symptoms:

Dizziness/feeling very faint

Feel like I am overheating

Nausea

Cramps in my lower left abdomen area

Lower back pain on both sides

Crying over EVERYTHING

Extremely tired

According to my app I ovulated on the 1st of March but according to my ovulation test I ovulated on the 24th February.

My period isn’t due till 16th March.

I did a pregnancy test everyday for the past 3 days and nothing yet.

Just wanted a second opinion!!! Does it sound like I might be pregnant???
