Advice needed !

A

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 are now getting sore, and my 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 !
