period after baby and still breastfeeding

can anyone share their period experience after baby was born and while they are still breastfeeding?? I used to hae terrible terrible cramps before I got pregnant....my son is now 7 months old and I have been breastfeeding this entire time...and just got my first period when he was 6 months...it came all of a sudden...no typical warning signs that I used to get...and was super light and then over in about 5-6 days...it has been 33 days since I stopped bleeding...is this normal??? what can I expect here??
