Hi Im new here, I have been TTC for a yr and a half and i just started trying the OPK's.... I had a positive result yesterday at 330pm but then it was negative a few hours later... today at 7am I tested positive again and 9am another positive!....(I was so excited that i had to check again)....my question is ....Is it normal for these tests to go pos neg pos? I know they can come out differently depending on the concentration of urine ....im confused ..and my husband is getting deployed in a week! this is our last chance for a little over six months. Should i consider myself O'ing???
