Breastfeeding and TTC advice needed

Hannah

Right I’m now 7.5 months pp and I’ve had regular periods since my first one at 7 weeks pp.. my cycles have changed to 33days and the periods are back to normal.

Anyways this cycle I’m late..I’ve tested and it’s negative..

I know breastfeeding can change my cycles and make them go weird but I’ve been so regular from the start? We are trying for another baby and I definitely ovulated!

Picture of this cycle. (We did have more sex than shown I don’t always enter it)

Should and when should I test again?
