Hi po ma! It’s natural to worry, especially with everything going on. Since you’ve stopped the injectable and have been experiencing irregular periods, it’s definitely possible to get pregnant, even while breastfeeding.
Breastfeeding can help delay ovulation, but it’s not a guaranteed form of birth control din po, especially after you’ve stopped your contraceptive method. If you’re feeling stressed and uncertain, it might help to talk to a healthcare provider who can give you more clarity and support. They can discuss your options and help you decide what’s best for your family and your peace of mind. :)
