Help ‼️

Okay guys here it is ....

Soo I ovulated from the Jan 30 - feb 7

I had sex Jan 31st and February 8th

My cycle is now going on the 4th day late

I took a test on the 19th negative

And today the 21st negative

Only symptoms is bloating and tiredness food aversions and moodiness

And also on like February 16th I wiped and it was a large amount of brown blood that went away immediately I’m 28 going on 29 in July so I’m just wondering could I be pregnant or what is some reasons for the delay in my cycle I’m not stressed at all .
