No period in over 3 months

Vanessa

So I had a miscarriage back in November and I've yet to get a period again since. I've read it can take a while for your periods to regulate again after miscarriage but how long should I wait before its concerning? Like do I need to see a doctor? I mean I highly doubt they would do anything. We are ttc baby #2 and I'm getting frustrated waiting for my cycle to return so we can continue trying.
