Second Beta, pain and negative thoughts

Beta came back at 855, which is more than double in 48 hour period. Follow up beta is scheduled for Saturday. Had a quick talk with my RE and he is as shocked and as we are. Yesterday I developed this dull ache on my right side. Since I remember having pain on the left side mid cycle, I’m almost sure that I ovulated on the left, so now I’m freaking out that it could have implanted in the wrong place and could be ectopic. I’ve read that it is possible although pretty rare to ovulate on one side and then have the egg travel to the other fallopian tube, but I wonder if it’s at all possible with didelphic uterus. Also, I’m freaking out that it may have implanted in my right uterus. During our prior TTC attempts, the embryo was place directly into the left uterus since my right uterus is practically inaccessible. I guess I should listen to my DH and take it one step at a time, which at this point means hoping and praying that beta goes up properly on Sat. I just find it hard to control my negative thoughts, especially with all these pains and aches raising my suspicions and driving me crazy.
