Confused!!

So I’m a bit confused. I have a very very heavy period and I can always tell when I’m on it. Monday was my first day off of ovulation. I had sex and after I was bleeding it stopped and I started spotting I have been spotting for 7 days now. The blood is light pink and some times light brown. I have no had any cramps, bloating, my bowl movement are not what they normally are during periods, my breast do not hurt and my period is 1/2 a week out. I know this is not a period but not really sure what it is. I have gained 7 pounds in 3 days!!!

My stomach is also very hard and bloated and I’ve been having horrible headaches.

Please help!!!

Doctor does not have an opening for another week!
