Need tips.

My boyfriend & I have had 2 miscarriages & an ectopic pregnancy. Afterwards, we tried on our own, but ended up going to CNY Fertility. We had 4 failed 'timed intercourses' that included a handful of meds & shots to the stomach, making me look like a punching bag. We discussed doing an IUI, which was $325 per time w/ no guarantees. We decided to give up after all the time of trying..... it has been a year & 3 months since my last pregnancy. AF didn't come by 11am which was abnormal. So I took 2 tests and they were POSITIVE. This was the only time I got to tell my boyfriend in person, since he was working every other time. On Friday I found out that we are 4w3d. I go back tomorrow for bloodwork & introlipids. But I can't get the fear of the past out of my head. When I pee, I'm always scared that I will see blood. Do any of you have any tips of how to cope, keep distracted, or what to avoid in general?
