Okay.. So me and my boyfriend haven't ever used condoms (I know stupid you should be protected) however I'm on my 33 day and haven't started my period... Yes I know I could be pregnant but he's pulled out perfectly in time a little bit before he cums. So is precum a likely chance? I researched late periods a bit and it said stress can delay it but I've been stressed before and been on time and eating habits changing which ive been eating less since school started not sure why. PLEASE HELP
