So I’m 6 days late on my period, yet I’m still getting my common PMS symptoms.. me and my boyfriend had unprotected sex about 4 times around my fertile window without condoms or birth control! What do you think? I also have been under some stress because of work.. so I don’t know if I’m pregnant or if the stress is delaying my period :( But I’m never late on my period, even when stressed. My cycle is always regular and I never been on birth control!
