So my son will be 11 months old next week and we are ready to start for baby #2. I was on the mini pill since my 6 week apt. I also breast feed so I haven’t had a period either. Recently quit taking my pills 2 weeks ago. How long did it take anyone in the same boat? Obviously I can’t track my ovulation but any advice how to besides the tests?
