Since it has only been a day I would not let that be a big worry. However, the fact that you had to nudge her to move from Second Questions that may or may not be a sign. It could be that she is not familiar with the way eHarmony works and that until both sides have exchanged the first OC message that you have to take turns and she may not have known that it was her turn. OR it could be an indication that she is not all that interested in you.

Just some musings on the phone call. To me mid-week means Wednesday. My cell phone works most anywhere in the country where people actually live. You don't call on Thursday because that is too close to the weekend. You don't call on Friday or Saturday because you don't want her to know that you don't have a date for the weekend and she doesn't want you to know that she doesn't have a date for the weekend. You don't call on Sunday because she is getting ready for the coming work week. You don't call on Monday because you are stressed from the start of the work week. You don't call on Tuesday because you have not gotten up the nerve to call. Hey I don't make this stuff up, read it in a book on dating.
