Shattered. Update

I've been trying to get pregnant for years in the process of trying I've lost four babies. The first one at 13 weeks with twins. second at 7 weeks and the last at 5 weeks. I'm truly just getting exhausted from trying. Mother's day is coming up and I've never felt more sad and alone in my life. I thought this month was it bc I actually feel pregnant but every test keeps saying no. I'm taking all my medications and I just don't understand why it won't happen for me. I have a blood clotting disorder with very low progesterone which I'm taking supplements for along with vitamins and fertility lube with using opks. I truly believe I'm done trying bc it's literally taking my happiness but on the other hand I'll never be truly happy until I can have a family of my own. I just needed to vent so whom ever took the time to read this thank you.

Update: started spotting 6 days before my period. Could the progesterone be making me spot or is it implantation or just my period. I never spot before my period btw.
