Extremely scared...help!

Hannah🌸 • PSOC/endometriosis sufferer with a past ectopic pregnancy, now currently pregnant with a baby boy💙
I have PCOS & Endometriosis, had surgery once before in 2013 to remove the cysts & endo and it all came back a year later. So I always thought there was really no chance of me getting pregnant..Last May, I had an ectopic pregnancy in my right tube for my first try at getting pregnant..my hCG levels came back at 50. I didn't have any symptoms of it until I woke up in blood; I was 5 weeks, 6 days. Now, last Wednesday I found out I'm pregnant again! YAY! As of today, 5 weeks 4 days. My levels now are 98..Just this time I'm having mild discomfort on my right side, not so much it being painful, but just an annoyance. I've felt this pain before when my cysts act up or around my period. It's more of a pulling/stretching feeling with very slight pain when I move a certain way or laugh, or cough. 
When I found out last Wednesday at the doctors that I was pregnant they did a pee test and both lines came in right away. He did an exam and said I have all signs of pregnancy & it feels to him as a normal pregnancy. I explained my fear & what I've been feeling on my right side and the doctor told me it could be my cysts acting up, my body changing & could feel this my whole pregnancy. Plus, I haven't missed my actual due period yet either. I went and got blood work done to conform the pregnancy & I go today for more blood work to check my hCG levels and an ultrasound to make sure the baby is where it is supposed to be and to find out how far along I am exactly...he also told me that woman who have had an ectopic before have only an 8-14% chance of having another one and an 86% chance of a normal pregnancy. I'm hoping I'm not the unlucky 8%! Wish me luck!!
