Hello Doctor. We had protected sex on 17 June. We used a condom correctly from start to finish, there was no break or leakage, and we even checked it afterwards. Her  period was expected around 30 June or 1 July, but it has still not come till today is 8th july . We took two home pregnancy tests that showed a very faint second line within 5 minutes, but another brand's test showed only one control line (negative). I am very anxious and confused. What do you recommend?
