Strange Cramping

So, for the past couple days I have been experiencing some stomach cramping that is unlike any that I have had. My ovulation has never felt like this and I know my period can't be coming now. If it is some kind of implantation cramping I would be very suprised because I dont expect to ovulate for over a week. I have not been able to take ovulation tests this month because my DH and I have been off doing holiday things for the past 3 weeks so I may have ovulated strangely early though. The cramps can be pretty intense but then sometimes they just turn into dull aching cramps. They are more all the way across my lower abdomen instead of on one side. This just makes me feel more worried and I am not looking forward to the end of this cycle because I feel like I know what the result will be...
I wish I could just be done with trying and have the pregnancy happen. I feel very negative about myself sometimes,like, when my period comes late and I test and again it is negative. Then I feel even worse about feeling bad that I can't get pregnant in the 5 months I have been trying when there are women who have been trying for years. I just feel like this experience is turning into something more stressful and unhappy than it should be. It should be about love and a happy experience. Sometimes I feel like it's more about having sex when I am ovulating and every other day than it is about having fun. I just never expected it to be hard on me at all. I see all these people around who accidently get pregnant from one unprotected moment and honestly I get jealous. I'm just having a frustrated day. I feel like I can't find anything new to make me hopeful because I am the kind of person to research everything and after the first couple months I did that and I haven't read anything new at all since. If anyone can help with encouragement and maybe some advice on the cramping I'd appreciate it... I haven't talked to anyone about my husband and I trying to get pregnant so it's definitely been a lonely experience.
