Hi mama! Spotting for 2 months after the injectable is actually pretty common, marami sa amin na nag-inject ang nakaranas nito, kaya hindi ka nag-iisa, but since it's been that long, mas maganda na i-check mo with your OB para ma-rule out kung may iba pang cause or kung kailangan lang ng adjustment sa dose mo, dahil bawat katawan talaga ay nag-react differently sa hormones. Some of my mom friends' spotting stopped after 3-4 months, pero iba tuluy-tuloy hanggang nag-switch sila ng method, so it's really best na marinig mo from your doctor kung normal lang ba for you or kailangan ng something else. Ingat ingat lang!
