Hi lovely. Yes it can, however baby blues is very common between 3 and 10 days. Anything that last longer than 2 weeks is more likely to be postnatal depression.
If you're feeling low, it's so important to tell your health visitor. There is a lot of support available and the earlier you get that support the better and quicker the recovery.
If you don't have an appointment coming up. Call your HV and let them know
Hope you are OK lovely 🌸
