Advice please!!!

Been ttc since jan 17, this last month we used pressed as well as opk! I was due af on 12/12 but started 2 days early was very light then stopped completely for about 12 hours then started again, lighter than usual but continued to bleed for 5 days and today when I should be finished I’ve started losing clots etc??!! I had a fall the day before I started bleeding, and wondered whether I could’ve had a little something setting up home for 9 months but the fall has disturbed everything hence af being early and very unusual (this has never happened before) any advice/opinions appreciated!

Don’t know what else to do, didn’t want to go GP in case it’s nothing. Thanks in advance xx
