Okay Mommas !!

QUESTION

I had a natural birth and my daughter is 7 months going on 8 months may 11th and my periods have been weird... like for example :

I had it 6 weeks after I had her. so in the end of October I had one.

Novemeber- I had one

December - I didn't have one. had it the beginning of January.

January - I had it

February - No period

March - spotted barley then went away

April - Haven't had it. I cramp every now an then

should I be worried or do y'all thing my cycle isn't back normal yet or?

I didn't breast feed. I supplied it But my daughter perfered the bottle.

But Opinions please?

I know I'm not pregnant, my period hasn't came in 2 months just spotted for a couple days and left. I took pregnancy tests. even went to the doctor and took one I was negative. should I be concerned ..???

my last pap I got going back to the doctor after birth I was perectly fine and clear. he said it could take up to 2 years to regulate again normally.
