late period :(

Jana

i am four days late from my period. i had sex two times unprotected during my ovulation week. ive been really stressed over the past 3 weeks and ive even been breaking out from it. also, i took a pregnancy test after being one day late and it said no. maybe that was too early to take? please let me know what you think/ what i would do. im trying not to panic because that would just delay my period even more right
