2 very very light periods since mc and I’m worried

Cee

I’ve had 2 very barely there periods since my mc. Had blighted ovum at 6 weeks and mc at 11 weeks. 5 weeks later period came and then another 4 weeks later. Both are only there when I wipe

Also my boobs have dropped a size and aren’t getting tenderness or sensitive as they usually would.

I’ve a ten year old and this mc was a loss but I just came off the pill which I was on for 5 months a progesterone one only .. and bam pregnant .. I was so happy

Now I’m 45 and terrified I won’t have anymore normal cycles as I always had, and I’m scared I’m infertile

All info is about heavy periods.. plz advise me girls I need your help
