I had unprotected sex with my boyfriend on days 13, 14, 15 and 16 of my cycle. On Day 16 I was feeling cramping.


I normally get symptoms of ovulation slightly later than this, usually day 19, as I have long cycles of around 30 or 31 days.


On day 20, I started cramping badly and having bleeding, ten days before my normal next period was due.

The bleeding got heavier and did not stop until ten days of bleeding had taken place.

What happened? Was this something caused by the sex, was it implantation bleeding, or was it a very immediate natural miscarriage?

The bleeding was so heavy I can hardly imagine any implantation would have survived it.

Any help would be good. I have not taken a home test as it seemed so much like a full blown period that I think it would be pointless, but I still would like to know what happened to me...
