HELP! Worried/confused! 😳 TTC/PERIOD

We've been trying to conceive for 12 months now. The first month ended in a miscarriage, and ever since we've had no luck. Any tips?

But here's the real problem..

My periods are always on time, and always light to medium for 3 days. So I had my normal period, same length, same flow.. and it had been gone for 2 days, no signs of blood or anything.. well this morning I was doing my makeup and being all energetic and confident, new thing I know I get this HORRIBLE crap around my left ovary and my stomach starts cramping. I started feeling a trickle down my legs, so I sat at the toilet and wiped.. I had a HEAVY stream of bright red and dark red blood flowing down my leg from my vagina.. could this be my period starting up? What is it? It's so heavy and PAINFUL! HELP!
