I had sex on 1/4 and got my normal period on the 17th. I am pretty regular and my period was supposed to start today but nothing. Now I have been under a lot of stress so it may be nothing. I thought my period would start as normal seeing that I had mild cramps for just a few minutes last night and have been emotional but that’s it. Normally I have sore boobs but I don’t/haven’t all week. Is there even a chance or is it just the stress?
