NOT SURE WHAT IT IS

Hello lady's, I have been with glow for a few years , been trying for almost 10 years to get prego , one successful try but miscarried at about 6 weeks and that was for years ago , I haven't give up hope , have gone to 3 fertility clinics on all this time but was told, on both last that they can't do anything for me as I dont produce enough eggs (I'm 46 now) , my question to you ladies not sure if anyone had gone through, but her goes I got my period on the 25 of December, I thought I was prego but got my period on the 31 of January, normal 5 days but o day 10 I bleed again for 2 days and stop , then I got my period on the first week of February and it happened the same thing, now I got my period , but my question its I'm 8 days left on the first time ,6 days on the second period ,so basically I'm getting my period o the 38 day or 37 , any comment or thoughts about ?
