I’m 4 weeks pregnant and got a positive frer 3 days ago, I took another today and the line hasn’t got darker. I also took a clearblue digital which said not pregnant and the internet cheapies are negative too. I have been charting my temps all cycle and this morning it dipped by 0.4, although it was much earlier than my usual time so may not be accurate. I’m scared there is something wrong, can anyone reassure me this is normal? I did get implantation spotting a week before I got the positive on frer.
