Need prayers...

Not sure why I'm still hopeful. Got first u/s done this past Tuesday. Not sure what my date is because cycles are irregular. But, had sex both on 7/29 and 7/31. Faint Positive came up on August 11after negative on 9th. That puts me around 6w3d on day of scan, or if I ovulated later in the week(like aug4) I could have only been around 5w3d or so. The report stated no yolk sac or fetal pole seen! I spoke to midwife today who said my beta is going up (went from 31000 ish to 39000 in 2 days) I asked about the gestational sac and she said it was poorly defined. Not sure what that means but googling it didn't help. Also, I asked what the sonographer was measuring because she was clearly measuring something in my sac and she said that it may possibly be product on conception since fertilization did occur. So, I don't want to hold onto false hopes. This all sounds bad, right? I'm frozen in my bed can't do anything else right now but research and cry. Have no appetite though I feel hungry symptoms of nausea and heartburn still getting to me. I wished for this baby and though I have two healthy happy babes I wanted to complete my family. My husband didn't want anymore but we had a couple of nights of let's see what happens and I feel like this is my last chance. I don't think I could go through this again and not sure that my husband wants anymore. We had already discussed vasectomy after this little one was born and now I'm mourning the fact that I'll never hold him/her. Never name him/her! I can't believe this is happening after two healthy pregnancies with 0 complications! Any prayers or comments help. Writing and chatting has been helping. Thank you for reading.
