Late Period Help!!!

Okay so lately I had a scare and I was 8 days late on my period and freaking out. I get AWFUL cramps and always like to know when I'm getting my period, hence why I have eve, but I was annoyed af by waiting 8 extra days to see when it would hit hard. So I asked my friends around what methods really work to start your period. I started the vitamin C method, you get full on vitamin C pills and take one each hour for 12 hours. I did it and the second day about halfway through the day I started! Another method I tried was the parsley method... well this is a little risky but I think it actually worked with the vitamin C. You take a parsley leaf (from the produce iasle) and you actually put it in your vagina for as long as you can handle it/ want it there. I've heard plenty people say they have had success with this! Just wanted to put out my input for people with the same problem I just did!!
