My period has come about 6 days earlier, I now have low flow, on/off cramp & blood clots. I am TTC, I don't know if this is a period or miscarriage? Light flow on tampons but when I get up from toilet there is clots in toilet

Vaginal bleeding ? Bleeding which occurs when attempting pregnancy may be related to a pregnancy not in the uterus (ectopic). Clots are not generally a part of a normal menstrual event at age 22. Obtain a serum HCG test to be certain about pregnancy. If negative, see your OB/GYN provider for an exam and testing.
