Thank you for your query.
After childbirth it is extremely common to have irregular cycles for upto 2 - 3 months, sometimes more.
If you are lactating, this is even more so - you would have delayed / scanty periods.
Also, you took Primolut tablets, which are hormonal
, so a cycle or two after that would be disturbed.
Since you have resumed your normal periods after child birth, it is best to start resuming a method of contraception
If you are sure you did not have unprotected sex, do not worry about pregnancy
It is natural for cycles to be erratic following childbirth.
Do consult your gynecologist to look for other conditions like thyroid or sugar imbalance, polycystic ovaries
, endometrial lesions etc.
Stress, anxiety, breastfeeding
, weight gain or loss - all cause irregular cycles.
