Rainbow Baby 👶🏽🌈??? UPDATE Miscarriage

So I found out I'm pregnant on CD 12. I had a strange period lasted 4 days 2 days of blood. 2 of very light. So I thought it was strange. Well it was cycle day 8 and I got a bright pink opk. I was like wtf. I always always ovulate cycle day 13-15. So yesterday cycle day 12 my friend tells me take a pregnancy test for fun and compare it. Welp!! There you have it. Bright pink and a digital. My last period before this was march 30 and lasted 7 days. Ovulation was April 12 CD14. opk and monitor read peak. I don't know if I ovulated later. But April 26 expected period nothing came until April 28 had those 4 days and then this cycle day 12. My only worry is that I took clomid CD3-7 this month and pregnancy was negative April 28 day 1 of my period so I stopped testing took clomid and now I'm pregnant. So I don't really know when I conceived. Went to doc today and did blood. Waiting on results. I hope this is my rainbow baby 🌈👶🏽 Due date based on my last true cycle should be Jan 5th. My birthday. This is truly the best gift after loosing my angel baby 12 weeks. Heartbeat stopped at 10w3days. Prayers needed and keeping faith. 

UPDATE

Beta continued rising. Repeated ultrasound and sac was found inside right Fallopian tube. I chose to take two injections of methotrexate to dissolve the pregnancy and about tube rupture and surgery. I have to wait 4-6 weeks for beta to drop.
