I give up

At this point .. I give up. I’m so tired of getting my hopes up every month as well as my husbands and then letting us both down. I’ve prayed and prayed! Miscarriage in August. Chemical in November and now these faint lines that you can barely see. I’m done with wasting money on test. Doctors day there’s nothing wrong with me but yet ... why am I not getting pregnant? What have I done to not deserve to be a mother?
