2nd miscarriage in a year

My husband and I have been ttc for the first time for the last year. In September I had my first miscarriage at 12 weeks and am going through my second one right now at four weeks. Both times I have had no Brest tenderness until the miscarriage starts and then they are SUPER sensitive. I’m just wondering if this is normal? What I’ve read says when the miscarriage starts that your hormones decrease so you should have less symptoms. Just trying to see if anyone else has similar situations or if it’s odd enough for me to bring up to my ob. Thanks in advance!
