actual symptoms or false symptoms

confused of am i pregnant..last unprotectiv intercourse was around the 4th&10th..so been 3 weeks of no sex..but as i have had symptoms as
-headaches
-small stomach pain
-frequent peein
-constipation
-very hungry for fruit
-hard to sleep some nights

weirdly las few days as the last week of june, the symptoms have gotten down..
-frequent peein but not as much used to b
would need to go about every hour but than cant pee at all
-constipation still
-hungur for mostly everything can find
but once i take abite i jus get hungry 4 fruit
-side pains but as much
would feel pain than all better
than 1/2 hour later lil’bit of pain again..

my period is verry irregular as i had my period twice in may, the 1st week for 3 days than the third week for 5 days. havent had it for about 6 weeks..since been off the pill since january, i’m thinkin that my body is going back to how used to b..as used to have my period only 2-4 months ayear

also i’m thinkin that i am having false symptoms ’cause i am confused thinkin that i mite b preg. as my mind is playing games with me…i have taken tests las 3 weeks n they all were neg..so it mite be too early still to take a test??as a blood test will be too early as well??i have taken one last week on the 25..that was 2 weeks after the thoughts of mite b preg.
