Hello ladies I'm a bit puzzled and need your help! So on 8/16 I had my period. I started testing for ovulation yesterday CD9 and it was low, today CD10 I took a test this morning and it was low, I don't normally retest the same day but my BBT was higher than usual this evening, I just took another test and it's a "steady" happy face!! Is this possible? To have a low result in the morning and steady face in the evening?
