Pregnant 7 months PP?

Ra

I think I could be pregnant with #2 but I am breastfeeding so my periods are irregular anyway. Anyone else that has had a similar experience? How long after conception did you test? Also did you continue breastfeeding? And do you still get colostrum if you tandem feed? Soo many questions 😬 Also had a c-section so if anyone has had a pregnancy this soon after a c-section I’d love to hear your experience as well!
