Odor?

I've been having a stronger vaginal odor since I stopped bleeding and am 9 weeks pp. I went to the doctor today and there's no infection... She said its because I'm breastfeeding! Now I'm super self conscious because I can't do anything about it... Any of you have this and have any remedies? I use a pH balanced wash and it doesn't help. 😟 Also, I've been so angry with DH for no reason, even though all he does is try to help! I'm either super angry or crying for no reason... And I don't even want to think about sex. I talked to my doctor and she said breastfeeding can also lengthen the baby blues. Ugh... Advice for how to cope with that would be appreciated too...
