I know it is quite possible to get pregnant if there's semen in pre cm. However, I am not sexually active and by my calendar my period is due on 23rd June. I have a 28 day cycle and this calendar is showing 26 before due date which is 23rd. A week before today, I engaged in foreplay/fingering (I am not sure of he touched himself before touching me). Been having heartburns (not frequent), no swollen/tender breast, no cramping, no mood swings, back pain (happens to me every other time), I am really stressed out from work and I have an irregular sleeping pattern( I sleep less than 8 hours daily).
