Trying after early miscarriage

So this is my first time trying after a chemical pregnancy. That affected me more than I thought it would. Artificial Inseminations happened on Friday, Saturday and Sunday. Peak ovulation was on Sunday. My app is saying 2dpo. I'm scared. I don't want to stress too much as I am scared if this happens then it will lead to another chemical. The last two weeks Ive felt the best I have for a while since the beginning of August. Sleeping better and eating better. Anyone have any thoughts or ideas that will help. Trying to manifest positive thoughts. My partner has been amazing through all of this just trying to keep me ca lm.
