When i was pregnant with my first, i returned 3 negative tests and two non responsive tests. At that point i was about 6 weeks. Dont give up hope just because the test doesnt show positive. The tell is with your af. If it comes you're not pregnant. If it doesn't, you are.
Did you have pms symptoms? Because i feel like AF will show anytime just bexause of the symptoms
I got one case of morning sickness but that was it. If i hadnt already missed my af i would never had known.
