Advice needed !

I am about 10 days late now for my period , thought for sure the week of April 28th-5th of May that I was going to get my period due to headaches, mild cramping , bloating, and lower back ache . They are all my before period symptoms but my period is still not here ! Cramping stopped on the 5th of May & I have had sore nipples since the 3rd of May which normally happens a day before I start bleeding but still not bleeding. currently still have bloating, headaches, lower back ache, the sore nipples, rest of boobs have started to get sore & boobs feel hot which is strange. Also have been needing some afternoon naps which I never needed before. plus noticed slight heartburn at night when I lay down. I Did take a clear blue digital test on Sunday May 5th but it was negative , took a cheap pee test at the doctors May 6th but she barely waited a minute for results , told me it was negative, and put it in the trash. could I still be pregnant & it was just too early to detect hcg on the digital test ? Should I test again ? Just finding it weird that I’m getting all these symptoms with no bleeding , definitely feel like something is off & I did have sex during the whole ovulation period using only pull out method & not on any birth control. any advice, opinions, or suggestions would be much appreciated !
