Cycle issues

Marquita

So does anyone here deal with heavy cycles ? No pains , only last 4 days out of the 6, blood clots ... Dr said it’s normal for some but my heart has me worried as if this may be a issue and may be the reason why I can’t conceive. I have a 9 year old I have been trying for nearly 3 years . My long ago ex and I separated come to find out he had his first healthy baby with someone else .. so I have been the problem . Now here I am with my current boyfriend that has no kids and wants one desperately & I know that I may be the problem as to why I can’t or won’t conceive :(
