Hi I am 5+2 weeks pregnant from ivf frozen embryo transfer. Had a mmc in feb also from ivf. I have been using the clear blue conception indicator and it still says 2-3 week from conception ie 4-5 weeks pg. I was wondering if anyone else has used these and if so when it went up to 3+ weeks. Had back ache and a few cramps at the weekend terrified I have had an other mmc.
