My period is 6 days late and I have a super regular cycle. I took 2 First Response test and there were clear but faint second lines , I took a digital it was negative. Tested two days later it was positive on a digital. The following day I had light cramping and very light pink brownish sometimes when I wipe. Cramping and pink color went away. I took all those test in the morning first pee. I just took another one now around 5pm and it was regular test not digital and the second line was so so faint like I can barely see it. Wondering if i miscarried?? Should I got to Dr for blood test and HCG levels?
