Late period?

Jemma • 3 beautiful babies
I just had my first period after I stopped breastfeeding around the end of feb/beginning of March. I was due to start my period again on the 29th (i think haven't had a proper cycle since before I got pregnant) but af is a no show. I'm having sharp pains on my right side around ovary, I'm slightly more tired than usual, I'm very grumpy, having crazy dreams, a lot of watery discharge and some heartburn. Do you think I should test or wait it out a couple of days? Do you think its a sign my period might be coming? I've totally forgot what I was like before af 😂 bar being a grumpy mare
