My husband and I have been trying to conceive for a few months. I have been taking home tests like crazy. I took 2 first response tests 5 days before my period and they both came back positive. I then proceeded to take 4 more clearblue digital tests, all which came back positive. I made a doctor's appointment for 2 days after my period was due (so I am 2 days late). Their test came back negative. Any ideas on whether I'm pregnant or not?
