Hi all, I got two thin lines on clearblue early detection tests, one a hour after testing another around twenty minutes after testing. Early bir swift test came back negative this morning. I have been feeling really weird, boobs have gone fuller and nipples changed, cramping, spotting brown and lightheaded with headaches - I never get headaches. Have been peeing a bit more and not getting sick but nauseous on and off. What do we think should I keep getting tests, do these look like Evap lines? Any information is helpful thank you so much.
