I am in the same boat.
I found out I was pregnant 4 days before my missed period & was in shock, I was so sure it was a false positive that I tested on 6 regular tests and 3 digitals and all came up positive! I’m now 4 weeks and 2 days and so far my boobs only lightly ache every now and again but nothing major. I get the odd rumbling tummy and little bit of back ache and frequent toilet trips but I don’t know if that’s because I’m now drinking more water.
Other then that I don’t seem to have many symptoms and it’s worrying me sick cause I just don’t feel like I could be pregnant
