Jealousy and TTC

I had been TTC for a year when I decided to just "stop" trying. I wasnt preventing pregnancy but wasn't trying either. I was shocked when I had missed my period. I took a test and found that I was pregnant... about 6 weeks along. I was so excited and relieved. One night I ended up in the hospital with side pains. That is when I learned I had an ectopic pregnancy. My doctor told me I had to wait 3 months after the 2 month long series of shots and blood tests ( 3 days a week)to try again. It has now been 8 months of TTC AGAIN and still nothing. I am getting very frustrated and scared. All I think about it not being able to have kids without IVF. My boyfriend is VERY supportive, but already has one child from a previous relationship. Sometimes it seems like he throws it in my face how easy it was for his ex to conceive. That is the LAST thing I want to hear at this point. I know he doesnt do it to make me mad or jealous, but it does. I am still going to continue to try and hopefully see 2 lines instead of one next month. Good luck to all!
