Confused and nervous

Rochell
Can someone please help me? I've taken a pregnancy test two days before my cycle was due but it was negative. I'm now three days late I've been really tired for the past two weeks and now my breasts are starting to hurt is it possible for me to still be pregnant? I'm afraid to test again because I just had a miscarriage 6 months ago and I'm afraid it may say negative. can someone please give me some advice. Thanks!
