breasts not tender anymore? bad sign??- help!

Ok so i am 4 weeks +1 today and the last days my breasts have been slightly sore and tender. Today i woke up and nothing!! I am so scared i am going to miscarry. I took another test right away but i am not sure if it is lighter or if there was just less dye in it cause the control line is lighter too. Any opinions? Is it normal? 
Side note: a doc will not see me before8 weeks so thats no option.
