Second opinion?

My boyfriend and I lost our baby at 12 weeks this past December. We have been trying to conceive for the past month or so. My last period was the third week of March. I started spotting in mid April, but that only lasted half a day. I didn’t spot again until earlier today, but again it only lasted a few hours and wasn’t heavy at all. I took a pregnancy test on Wednesday 5/2 and it came back negative, but I also got a false negative with my last pregnancy in the very beginning. Has anyone else spotted a little shortly after conceiving? Do you think I might be pregnant again? I’m going to wait until Wednesday 5/9 to test again, but I just wanted some other ladies’ opinions because it’s all I can think about and the wait is killing me 😅
