Pregnant while nursing?

Va
I haven't had a period since November 2013 and I'm trying to conceive. I bf my 8 month old and give him solids more and more each day. I just started feeling signs of cramping and mood swings and period symptoms (but no period) just this last month! Anyone else going through the same or have been through it? Is there hope! I love nursing and won't stop until my baby is ready.
