Scared to test

Amanda • My husband and I got married in 2012, we have a three year old boy and welcomed our rainbow baby girl March 2017 ☀️🌈
I miscarried on April 7th, I was 5 weeks. I ovulated on the 22nd and now I'm 19 dpo and still no period and very light cramping. I also took a pregnancy test around the time I ovulated and it came back negative so we stopped using protection. My boobs have been sore for the last 10 days. I'm scared to test because I'm trying not to get too excited. I know it can take up to 6 weeks to get your period back.
