So I took a frer 2 days ago and there was a very very faint squinter line. I took one again today (2 days later, 10dpo) and there is again a VVV faint line. Shouldn't it have gotten darker after 2 days? Could it be a possible chemical pregnancy or is this quite normal. I also did an internet cheapie, the hcg line lit up as was going across but when it dried it was a VVV faint line.
