I’m late... Back to back babies?

T

I am 6 months (will be 7 months on the 11th) pp and I’m now 4 days late. I have not taken a test yet (partially because I’m afraid it’ll say positive😬). If anyone has had babies this close in age what were your pregnancy symptoms if breast feeding? I feel like i can’t go based on if my boobs hurt or change size because I’m nursing. Trying to wait it out a while and see if my period is just out of whack this month due to nursing and hormones.
