My boyfriend amd I were dry humping with clothes amd he ejaculated. I had a tampon in to prevent spotting because it was the last day of my period. We were fully clothed!! Him in underwear and kakhis, me in underwear and leggings. Im so terrified of being pregnant! Ive had loss of appetite, tender breasts, nausea, now im out of breath doing anything like walking up the stairs. Im also super fatigued. Is there any chance of pregnancy? Is this all in my head?
