Cant help too much here hun, except to say that after bub, AF can be really irregular, even months apart. I am sure there are plenty of women in here who can attest to that. As for me, I didn't get AF until after I stopped BF, about 16 months after DS was born. Feeding can delay things, and maybe the initial AF that you had might have been some post-partum stuff instead of ovulation.

If you are concerned that you might ovulate unexpectadly, you might need to watch carefully for signs so you can monitor your cycle without having to do too many tests (which are expensive).

Good luck hun.
