Please help 💕

Hi! We've been trying for a few months but after last months disappointment I decided not to worry too much or try to plan everything, just relax and trust that it’ll happen when it’s time to. We didn’t try too hard this month, it was just once or twice after ovulation and not keeping track like before. I've been using Flo to log period dates, and my period is a few days late now. Last period was on 02/11. My period is now 2 or 3 days late. I had a negative test a few days ago before it was actually late, so thought it might be because it was too early - I tested negative again yesterday (27/12). Both times using ClearBlue (not digital). Followed instructions correctly and saw the negative after 5mins. However, I looked at the test again hours later while tidying up and saw a new line… I know this is most likely an evap line, but is there any chance that it’s not? My period is never late. It's so heartbreaking praying for the positive and getting our hopes up to be let down again isn’t it? I'm looking for some help and advice, and thank you for reading ❤️
