Af started today

i am so bummed....... I thought for sure since dh and i were very active this last month that it would have happened.. However i don't thing my cycles have regulated themselves since we had evan in august.
My cycles used to always be 28 days apart and last 2-3 days now they are about 33 days apart and last one lasted for 10 days. Hoping they will regulate so i can detect ovulation soon!!!!!
