Anyone else skipping periods due to EBF?!

TT

Kinda weird with my first I EBF and got a regular period, that was 5 years ago also intercourse was dry like a desert 🏜🌵 my baby is 5 months now and I’ve only got 1 period right after my 6 weeks postpartum since then it’s nonexistent, I’ve felt some cramping but no period, EBF this time as well but I am lubricant naturally done there, don’t know what’s going on ?! Should I see my dr ?! Trying to cut calories little by little as I am overweight by like 30 lbs my supply has dropped since the 4th month sleep regression baby seems to be ready for solids. Don’t plan to have another baby anytime soon. Really wanna focus on my weight, want to take an all natural fat burner equivalent to a half of cup of coffee. I know I’ve went off topic lol 😂 someone talk to me 😅
