Confused about next ovulation date

Question

Here is the back story... My last period was July 12th and lasted 5 days, I should have ovulated on July 26th. We BD'd daily July 23th-July29th. I should have started my next period on August 8th. On August 6th I started having some very light bleeding only when I wiped. On Thursday it became pink and brown and looked like there was more mucous in it then blood. That stopped over night on Thursday and was sparatic until Friday evening and then stopped again. My doctor said that it could have been implantation and asked me to come in for a blood test on Monday morning. The blood test came back negative. I still have not had a regular period and do not know how to find out when I might be ovulating next. Any suggestions?

Answer 1

Doctor could run more blood work to see what's going on.
