Unexpected pregnancy after 3 losses last year

A little background: I am 26. Last year (2022) I experienced three miscarriages. The first was in February at 11w3d , the second was in September at about 8 weeks, and the last was in November at about 6 weeks. After our last loss, we decided to be very careful and to try not to get pregnant again til after we got some testing done. Our testing is scheduled for next week. Today, I was feeling a little funky. My boobs have been hurting and I’ve been exhausted. I wasn’t supposed to get my period until tomorrow, but I asked my husband to pick up a test and it was positive.

I am filled with so many emotions. I don’t know if I can still get testing done while pregnant and I’m so scared. This was a complete accident. I want to be excited, but I am obviously apprehensive because of my prior losses.

So, if anyone has advice or suggestions on what to discuss with my doctor next week; if there is any testing I can ask for while pregnant; any vitamin or supplement recommendations; really any recommendations at all on things you did differently when pregnant after loss. Also words of encouragement would be really appreciated.
