I took a few tests last week with first response. They were very faint but at 3 days apart i had one get a little darker. Today i decided to take one hoping it would come up even darker but now my lines are super super faint to the point where you can barely see it. I took one in the morning and one at night. They are both so much more faint than the ones from last week and im very concerned and sad. Can someone reassure me or give me some advise please. If i was pregnant today id be 3 weeks and 1 day.
