Right after havin sex w/ my bf i had 2 big clots come out i had spotted a little a day before and i have been on it for 4 days its been dark n clumpy ?

Not normal: Vaginal bleeding after sex always needs to be evaluated to make sure there is not a serious issue. Please see your gyn.

Did you have sex: Before , during or shortly after your menses ? If this is the case you need not to worry . If it happened in non menstrual period , i would recommend to watch the bleeding and any other symptoms like pain , fever and others very carefully and talk to your doc. Good luck.
