Stressed

Hey ladies, I’m going to try and make a long story short. On the 16th of may my 14 year old son was badly burnt in a fire. We were rushed to the nearest major hospital for treatment. This was an extremely stressful and emotional time.. 2 weeks later I had a feeling I was pregnant and sure enough a test was a faint positive. The next day the test was darker, the next day the line was lighter. The next day I did another test and it was so faint, by 2pm just after my sons 4th operation in 2 weeks I started bleeding hard. I suffered a cp, I bleed for 1 week and was fine. But my breasts this mth started to get sore again. My son is out of hospital now and when I got to see hubby again wellllll we bd. So I have had sex. I just did a test and it was the faintest pos. Now I am freaking out because I have a history of ectopics, my son will still need treatments. I’m stressing again but I know stress isnt going to help... but seeing a pos test 3 1/2 weeks after the chemical I am freaking out about this baby being ectopic or not sticking
