So upset

Can you have vaginal bleeding and still be pregnant? I just got my period today and I'm so upset.. I've been having all the symptoms the head aches, back aches, dizziness, morning sickness and my boobs ( mostly nipples) hurt so bad.. Every month is disappointing. I feel like I'm never gonna be a mother. My mom said she had vaginal bleeding with me when she was pregnant so I guess I can make an appointment to see why my boobs hurt so bad
