Pray for me!!!

I had an ectopic pregnancy last year, unfortunately I lost my left tube. My doctor strongly recommended the Depo shot and I did. Now I haven’t been able to conceive. I changed my OB doctor a couple of months ago and he got me started in the Clomiphene. I took the 50ml the first month and I didn’t get my period for 50 days. First I thought I was pregnant but my LH level was low. My OB again prescribed Clomiphene 100ml and once again my LH level was low. Now, I am four days late and this time I am having very different symptoms. My breast hurt very much I am tired around noon time and I’m also cramping. Would it be my period? I took two pregnancy tests already and both were negative. I don’t know what to do. I’m losing hope😞.
