My gf's period cycle was 28-29 days ... On December 9th 2023 a protected intercourse occurred on her 6th days of cycle after that bleeding occurs in 1-4 th Jan ,2024 ... On Jan 9th we met that time but no penetrative sex occured, only oral sex happened and ejaculated semen was on her breast and chest area... After that Feb 1- 3 th 2024 her bleeding happened.... But problem is on today she has started bleeding and today is her 21 th day of his previous cycle... Is it possible to have pregnancy! Please clarify we are really worried to much
