Strange period..?

So I usually have irregular periods and me and my boyfriend are trying to have a baby. I started taking femaprin to help bc I've heard it does wonders. I took it for two weeks and got a period! The problem is that I spotted for 3 days and I've been bleeding heavy for 10 days and I'm still bleeding. I'm not sure if this is relevant or not but before my period I had a yeast infection that lasted over two weeks and it would not go away! I used Monistat for 10 days and finally started to stop itching and burning! This period has been really strange though because I have been lightheaded non stop for the last 5 days. I also normally don't have blood clots and I've had at least 10 this period. I've also had a lot of headaches and abdominal pain and now I just feel like I can not wake up! What should i do??
