My period has been irregular since having two miscarriages back to back two years ago. I have been unable to conceive since then.?

Ovulating? Irregular periods would indicate you are not ovulating regularly, which makes conception difficult. Your miscarriages indicate that you have been able to conceive in the past, which is encouraging. You may have hormonal changes that are causing problems with conceiving. Consult your doctor who can evaluate for causes of infertility and review options for treatment. I wish you luck.
