Hey mama! Honestly, it varies talaga, some of my mum friends got pregnant agad after 3-4 months, while iba ay tumagal ng 6-8 months bago bumalik ang regular cycle, kaya really depends on your body. Since you've only had 2 shots, your fertility should bounce back relatively quickly, but best to check with your OB para sa peace of mind at para ma-track din nila kung regular na ulit ang periods mo, they can give you a better timeline based on your specific situation.
