Pregnancy after misscarriage

Sarah

I have been taking pregnancy test off and on after my misscarriage to be sure my numbers went back down. I should of been around 12 weeks when i pass the baby. My bleeding started 4 weeks before that off and on my full bleeding started 2.5 weeks before. The baby past at 6.5days. Also past what was supposed to be a molar pregnancy mass a few days after passing baby. So i know you can ovulate just a few weeks after.and because my dr gave me all clear to try again i took opk and it was positive...so i took a hcg test too just to see..it was a super faint line so i kept taking both days later opk faded as they should after ovulation and so did hcg...few days ago the hcg was so faint its was like a shadow...today took them again just to see...the opk as it should be the hcg still faint but darker then days ago...?? Today would only be 5 or 6 dpo has anyone ever had this and end up pregnant again.top and left are today others are 2 days ago
