No period to be seen

Ida

I stopped breastfeeding almost 6 weeks ago after breastfeeding for 20months and I still haven’t gotten my period back.

I’ve had cramps and tiny bit of blood when wiping sporadically over the the last 6 weeks but no period. My body is aching and lower back killing me, mood off and it’s just taking a toll. I’ve done lots of pregnancy tests nothing. Anyone think it’s time to see my GP? Or just wait and suffer lol. TIA For any advice 💛
