Diet / periods late

Alex

Okay so first things first. I’ve never really had regular periods they are always a few days apart and sometimes 6-8 days late. I noticed that when I drink a lot of coffee it’s tends to be late. This month is the second month I’m using flow and it says I was supposed to start on the 28th but obviously it’s now the 8th and still nothing I drank A LOT of coffee this month like everyday sometimes twice a day I’ve had minimal cramps very spaced out I’m having my normal mood swings but no period !???????? I have been stressing and I know that’s also a factor I don’t think I’m pregnant me and my boyfriend use a condom every time and check it every time we only had sex twice this month so likelihood is low. My question, is there any way to induce of kick start a late period.
