Period problems

I don’t know where else to post but me and my fiancé are wanting to have a baby and we haven’t been successful the last two tries and now I have my period and it is super heavy and this morning I actually ended up passing out. I’m not sure if it’s from the amount of blood or not, before my period started I was getting severe cramps to where I’d be bending over in pain. This period is different than any others I’ve had, I’ve never passed out because of my period before. Is this normal? I don’t know if I should go to the doctors or not.
