Scared to test early incase I have another chemical :(

Me and my partner conceived last month and I tested 1-2 weeks on a clearblue. This app told me to take a test. The next day I went to Dr's they confirmed a negative. 3 days later I done a clearblue and it was negative. Doctors said that it was a chemical pregnancy. I have so mich anxiety since this happening and keep scaring myself I keep reading up things about failed implantation ect and it's scaring me so much. Were going on a trip the day my period is due and some of the activities that we are doing aren't advised for pregnant women. My partner suggested we do an early test and see what happens then obviously if I am we will cancel activities but if not pregnant we will go ahead. The thing is though I'm scared to test to early incase I get a positive then have another chemical and I'm scared incase I don't test and do the activities and am pregnant and end up harming the baby or causing another chemical or misscarriage. I feel like I'm in a horrible situation we've paid a lot of money to do these things as well and I just don't know what to do. Any friendly advice please no horrible comments.
