I have recently become ORALLY sexually active with my gf on the one instance she sucked my private part afterward i touched himself and after few minutes I fingered her vagina with the same hand so afterwards she took ecp and after taking ecp she got her period after 3 days of delays she bleed 4 to 5 days she said it was like her previous period so my question is that was her period or withdrawal bleeding and what are the chances of pregnancy in this cause and what other side effects I should know Note this happen after 21 days after her 1st menstrual bleeding was this her safe period And also she has taken ecp in the month of November 2019 after consulting gyno will it have any effect now and was it safe to take ecp again after this  time interval Can pregnancy can be caused in this case.
