Night Sweats

I miscarried 5.5 weeks ago & had night sweats most nights for a few weeks then they stopped. They seem to have returned the last 2-3 nights.. is this normal? I’ve just finished my first period of that makes a difference..? I’ll see a GP eventually if they continue but as they’re not causing me anything other than an annoyance I’m holding out. The photo was 3 hours after I went to sleep.
