Pregnancy test


I missed my period about 3 weeks ago, I took 2 pregnancy test on different days and they both came out POSITIVE. I’m a little skeptical only because 1 year ago I had chemo and I really thought I couldn’t have kids after that and also because I’ve heard mixed reviews about these clearblue tests. The only symptoms I feel are mild cramps, constipation, hunger and sleepiness (more than usual) Has anyone else been through this ? I really wish I was pregnant.
