Okay so I been testing everyday from cd 10 and then when I got my positive on cd 15 I stopped testing. Well today cd 21, 8 day before af and 6 dpo I tested again because I didn't want to test with a pregnancy test. And wanted to see because I have been getting little pinching feeling on my right side that feels like needles. I know that the first positive on cd 15 is really a positive but what about the one I just took because it is the same color as the control line? Any ideas?
