Could I be pregnant?

I had been feeling strange for about a week or so. Very dizzy and extremely tired. Had mild cramps about a week after my supposed ovulation time. Tracked CM and had good signs for this month.

I was supposed to get my period on Friday- July 13th. Usually my boobs are extremely sore for about a week before and this time nothing. My “period” was 3 days late.. I didn’t start until Monday. There was some bright red blood. But not nearly as much as usual and no cramping or any other normal pms signs for me.

I only bled Monday and Tuesday. Yesterday it was just some very light spotting and nothing today.

But last night and today I have been very nauseous. I took another test today and it was negative.

I’m wondering if any of you experienced something similar in early pregnancy or if this was just a weird month for me..

I know this sounds crazy but I just “feel” pregnant. But according to my test I’m not 🤷🏽‍♀️
