Devastated more than usual

My husband and I have been trying to conceive with baby #2 since January. At first I wasn't using anything to try to help me through this process, but by month 3 I started using OPKs. I was confident and clearly knew when I was getting positive tests, and I know they aren't going to actually help me GET pregnant but it gave me hope. Then I got my period. Oh well, after many tears, I decided to try the lubricant PreSeed, something my friends all said they tried and it worked for their first or second cycle. So that was this month ALONG with OPKs so in short I got my hopes up so high and I kept telling myself that "this is it, this is the month I get pregnant, Im finally going to have another baby and give my son a baby brother/sister".

Today in the afternoon, when I was just going to take a pee, there it was, a bright red bloody mess in my underwear. I immediately couldn't believe it, and started bawling my eyes out. My husband is home and tried to reassure me that next month dear, next month it will happen. Hes been saying that since we've been trying and it angers me instead of helping. And all the while my son is being needy and wanting me to be with him (1 1/2 yrs old). I just couldn't and told my husband to go with him and take a shower with him. I had the worst crying fit in years, to the point of hyperventilating and dry heaving, all that ugly stuff. I just keep wondering why, why, and what am I doing wrong?!

I know I have only been trying for 5 months, so I may be overreacting and being emotional especially since I did just start my period but it's so devastating, I just want another baby, why is that so hard for people who want children to not give that to them?

I really needed to vent. I try to vent to my husband but he says its basically my doing that I'm not pregnant yet. He may be somewhat right, but does he really need to say that to me literally only an hour after me getting my period and my hysteric fit that he chose this time to tell me this? And that I need to stop being sad already? That I'm stressing myself out and thats why it hasnt happened yet, and that its me doing these opks and preseed is me trying to control to get pregnant and its not up to me. I know that in a sense it isnt up to me, but I don't think me trying to help the process along is why I'm not getting pregnant.

Not sure when would be a good time to go to the doctor either to check if its me or him that may be hindering us TTC. I know it can take couples 6-12 months to but it only took 2 cycles for my first. Again just venting and sad about everything right now :(
