Hello just yesterday I found out I am pregnant. This was a complete surprise. I was about 2-3 days late for my period when I tested and the 2 lines on the test came up straight away and were very dark lines. I’ve just done another test with a different brand and again it’s come up immediately with a strong positive. According to my dates I am 4+4 weeks. Would the tests have such dark lines at this stage in the pregnancy? I have 3 older children but haven’t been pregnant for 12 years.
