Third week on my period

So I schedule a doc appt bc my period came on and I wanted to take clomid to get pregnant. I used clomid for my first pregnancy and it went well. The second time it didn’t take so they boosted me to 100 mg. It worked but shortly after I miscarried. So here I am popping 100 mg of clomid on day 5 of my period, take the pill for 5 days and my period gets light. Shortly after running out of pads I reluctantly get more and now my period is heavier than ever. I am going into 3 weeks and I’m so bummed. My fertile window is approaching and slowly closing. And there is nothing I can do about it but bleed🤦🏽‍♀️🤦🏽‍♀️🤦🏽‍♀️. I just want to be blessed with many children of my own.
