Trying for baby #2 already!

So my husband and I would like to start trying for baby #2 I’m 5 months pp but I haven’t had a period since the 11/01/18 so I have no idea what to do 😅 should I try ovulation tests to see if I’m actually ovulating or 🤷🏼‍♀️ (I should also add I’m exclusively breastfeeding too)
