So I had a chemical pregnancy in november, by december 13 my period had come back and it was the usual 5 days it always has been. But now my period is 17 days late and if my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period calendar</a> was correct i did have sex on my ovulation day. My boobs get aches here and there, and i’m very tired. But all my tests are still negative. Should i test again or just get a blood test?
