I had my son 4 months ago. I started my cycle 6 weeks after birth (same as when I had my daughter 2 years ago). I typically have 25-29 days between periods but I'm on cycle day 34 right now. Its unusual for me to be late. I took a test this morning and it was negative. I plan to test again in a couple of days if my period still isn't here. Im having some nausea, breast tenderness, milky discharge, and light cramping

Has anyone had random long cycles? Does breastfeeding delay a positive pregnancy test?
