On the 12th I had sex and my partner pulled out and took off his condom and finished on my body. I don't think any of his cum got into or close to my vagina. If anything it just got onto my mound. That day he got me a vape pen and I have been smoking the weed since then. This is unusual for me because I never smoke. Now I'm four days late and i don't know whether I'm
pregnant or the weed affected my cycle. How can I induce my period?
