my partner and i had sex a few weeks ago and we used a condom and i did not see any signs of breakage but my period is 4 days late. i track my cycle on clue, if you are familiar with it, and it says that we had sex before my ovulation but i am still concerned, i have had a stressful month with job hunting, money issues, and my partner moving in temporarily, and i am looking after a cat which is new for me but stress never seemed to influence my cycle before. i am unsure if this is just something new or if i should be concerned, and i i should be what should i do?
side note i am not on birth control and i am 19
