TTC after 5 years of 2 ectopic pregnancies

I had 2 ectopic pregnancies in the space of 9 months back in 2013. I was 30 years old at the time. The first ectopic was managed by methotrexate. The second one was managed by expectant management. I went for a hysteroscopy in 2013 and there was nothing wrong with my uterus. In 2014 i went for a hsg test. Everything came back normal. No blockages. The dye went through the tubes swimmingly. I have a daughter' who is almost 13years old, so i know i can conceive and have a healthy pregnancy & birth. After 5 years, 2018 i am now 35 and trying to conceive again. I am currently on my two week wait and i feel like i am unsuccessful this cycle. My cervix is low and firm at 3dpo and I have been getting cramping since ovulation day. So my donor is now aware i am probably not pregnant and will need his services again for next cycle. I feel like i am a failure to myself and my body. I am really nervous incase i have another ectopic pregnancy. I have recently quit all caffeine this includes chocolate and soda, i quit all soya/soy. All i eat now is healthy food and drink roobios tea, orange/pineapple juice. I take my folic acid tablet each morning.
