Pregnant again after a miscarriage and terrified. (Long post)

I have a daughter that will be 3 in Jaunary and I miscarried last year with my second pregnancy at 11 weeks. I wasn't up for trying again right after so I got on birth control for 7 months and we had been trying to get pregnant for almost 8 months.. Well, last Saturday we got 3  faint lines and then a pregnant 1-3 on a digital. On August 23rd I went to the ER in severe pain.. They did a cat scan to check my appendix and found that it was a infection in my colon instead.. The cat scan also said that I had a midline retroverted utuerus and small 2.5 cm follicular cysts. My last period was August 1st but as of the 23rd the test they did came out negitve.. I asked the nurse a question about me CT so she looked up the CT and said that I had a egg forming in each ovarie.. Which means I wouldn't have ovulated yet right? Or could she see the follicular cysts and mistaken them? Because that would mean I ovulated late but would have had to ovulate that night of the next.. My pregnancy is going by my last period but if the nurse was right then that isn't correct.. I was also put on 2 very strong antibiotics, pain meds and zofran for a week. I finished them on the 30th and missed my period on the 1st/2nd. I am so terrified I will have another miscarriage. Every time I go pee I have to make sure I'm not bleeding when I wipe. My first DR appointment is 10-5-16.. According to my last period I will be 9 weeks then and I will be getting a ultrasound that day. My daughter keeps asking for a sibling and would be a an amazing big sister.. I just want this so bad. Any advice of encouraging words would be a amazing! Thank yall for reading this long post!!
