Son just turned one and I'm still not back to normal cycle!!

My son turned one yesterday and we had wonderful celebrations. We are still breastfeeding once a day, first thing in the morning and intend to gently wean from this one by the end of the week. We have slowly weaned the other feeds every two weeks so it has taken approximately 6 weeks to get to this point.
My husband and I would like to concieve our next child sometime mid year. I am confused as to what my body is up to however as a couple of months ago I had a light period but have not had one since. I have done a home pregnancy test just in case, even though I have been taking the mini pill, but it was negative. I haven't felt any of the same pregnancy symptoms as last time except wanting to pee more.
I am just wondering if the mini pill or breastfeeding could still be upsetting everything and if I can expect a return to normal soon.
It makes planning so much harder when I don't know where I am at. :-k
