Is it normal at 4 weeks and 5 days to have vibrant positives even if you take a test at night? If I take a test in the morning the result line will be much darker in comparison to the test line. Also my boobs have gotten so much bigger and my nipples are so perky and hard they hurt. And I'm so tired that I fell asleep at work and the nausea has hit me like a train. I was doing a <a href="https://glowing.com/glow-fertility-program">fertility treatment</a> but the treatment wasnt hormonal and there were two mature follicles on our last scan. Could all these symptoms mean that we're having twins?
