First postpartum period?

Please help, I had my daughter 7 months ago and have yet to get a postpartum period. I just want one to get back in sync with everything. I’m actually a little unsure why I haven’t gotten my period. I have been breastfeeding but not exclusively and have been feeding my daughter formula supplements (since she was 2 weeks) and solids (since she was 4 months). I am feeling super bloated right now so I’m hoping this means my period is on its way. Just want to know what your signs were.
