ADVICE PLEASE? pregnant after 2 chemicals, keep expecting to see blood in my underwear like the last two times :(

Georgia

so I found out I was pregnant 2 days ago at 8dpo (3w3d, now 3w5d) and since then I've been a nervous wreck! I've been having slight cramping and I keep going to the bathroom because I'm terrified that I'm going to lose this baby too. my last chemical was 17th July and I haven't had a period inbetween, I've fallen straight away at ovulation 2 weeks later. guess I'm just a nervous wreck the top two pictures were taken from this pregnancy and the bottom two were my previous cycle at 14dpo (day of missed period) and 15dpo.
