I don't know what to think....

Me & my life partner have been trying to conceive every since September of last year. We however did luck up and she was pregnant on our first try but we lost the baby. She was disconnected from me for awhile and now we are back at it trying once again. However I know it's possible too early to test but I really want to know but I don't want to feel like I'm jinxn us.....sighs. I don't know what to think because ever since we have been trying she really doesn't feel in the mood to have sex. I mean I try everything I can think of to put a smile on her face but still at the end of the day I find myself in bed alone cuz she rather sleep on the couch because she says it's comfortable to her. She always has an excuse for why she doesn't want to be sexual yet when I'm off to work she texts me that she hm self pleasuring to go to sleep at nap time. I'm like really. ...her explanation : "That's my normal routine at nap time to relax me" , my response: " But what about me, I can do that too" Sighs.....really fustrated, Any Insight ladies?
