Help: bleeding after period?

Keishly
Has anyone bled a week after their period. Exactly a week after I had my period. I tested peak on a OPK test since I spotted a bit, light pinking blood not too red then later that day I began bleeding, heavily bleeding as if it was another period...went on for about 4 days/no cramping...and once I thought it was gone my husband and I babydanced and a blood clot, a single blood clot, comes out. 😖 and I haven't bled for about 4 days now, yesterday my husband I baby danced again. Everything good, but now I'm having mild pains only on my right side abdominal area. Am I ovulating again sooo quickly? Or idk what CD I am anymore because of the bleeding in between....I'm so confused...has anyone gone through this? 
**We are TTC for close to a year now, had a HSG test two months ago, turned out normal.
