I’m about 5 days late on my period, I had sex on the 25th of November and it was my most fertile day, In cramping bad, back pain, boobs are so sore to the touch as well as my nipples, I’ve been falling asleep by 7:30 every night, I took a test today but it was negative, is this just a late period symptoms? It’s just so frustrating how much pain I’m in and not feeling good..
