hey, I had incomplete sex with my boyfriend on 22nd November 2015,he ejaculated outside and just after ejaculation I washed my vagina .after 2 days I had my periods and I took even i-pill in periods only and the bleeding was quite thin like water blood was flowing not like my usual periods. no clot of blood was there and the colour was lighter. it lasted for 7day.I became normal after the periods but suddenly on 10th evening I had sudden vaginal and abdominal pain that too very strong.I m afraid now that I m pregnant??what to do??
