Exhausted!!!

I am having one of those "rough" days and need to vent! DH and I started this journey 2 years ago when we decided to try for #2! I had complications with #1, freaked out, and tied my tubes! So I had surgery and had them reversed! HSG on OR table came back successful. 6 months late we had an early MC. My surgeon wanted to make sure both tubes were still open so he ordered another HSG a couple months later. Then placed me on Femara. 2 cycles later (6 months post mc) BFP. Then sadly another mc at 9wks, fetus stopped developing around 5-6 wks. Devastated I took a break from charting and OPKs but continued to pay attention to O signs and a lot. After a 71 day cycle I was diagnosed with PCOS and Insulin resistance. So now I'm Metformin 2000mg a day. My fertility specialist is very convinced we will get pregnant quickly now, and he kind of got my hopes up. He gave me a couple months to get pregnant on my own with the Metformin and if I am not pregnant by his deadline he is putting me back on Femara. I thought this cycle was it! I had a beautiful dip in my temp on 8dpo followed by a pretty significant rise. And my breasts hurt so bad I am having trouble sleeping (been awake since 4am) and I just want to cry. I threatened to squeeze DH's man parts because he jokingly threatened to poke my breast! But here I am 13dpo and still BFN! I had another dip on 12dpo but it went up again today, but I tossed and turned a lot and the temp was 1 hr earlier than I normally take it. I'm just so tired! I'm tired of the charting. I'm tired of the waiting. I'm tired of everyone around me getting pregnant with ease or without even "trying." I feel like a failure because the 1 thing I should be able to do as a woman...I cannot! I'M EXHAUSTED!!!!! It's been 8 months since my last mc...I am beyond ready for my Rainbow Baby!!!! So sorry for whining but I needed to get it out. Thank you for reading.
