"The K3 Visa Family Unification Process: How Is It Working for You? Questions from CIS Ombudsman's Teleconference on January 31, 2008
The following are questions discussed during the January 31, 2008 teleconference and the answers received from USCIS.
1. Administrative Closures of I-129Fs? – One caller noted that USCIS’ National Customer Service Center is providing different information on the I-130/I-129F process. One customer service representative stated that the I-129F is administratively closed after the I-130 is approved. Another representative stated that I-129Fs are not closed and USCIS is continuing to process the I-129F. Is USCIS administratively closing the I-129F application if the I-130 has been approved? Can USCIS provide clarification on this process?
USCIS Response on April 30, 2008: USCIS has been administratively closing the I-129F upon approval of the I-130. USCIS, however, is currently reviewing the I-129F/K-3 process."

Try to stay calm and find out if they have cancelled your 129f. Some people are allowed to choose between K3 and CR1's and other are not being given that choice.
There are a few people on the board that have gone through/are going through this.
Good luck
