Could my hamster be pregnant?

Is it to early to tel if shes pregnant? My hamster?

• She is a chinese dwarf hamster a opal one. She has always been chubby. She is one and a half years old. Well wednesday night i took my hamster(female) to my friends house she has a chinese dwarf hamster who is a boy. I watched the two they seemed not to like each other. I swear i watched them like a hawk. UNTIL.. I put the two in the DRY bathtub why'll me and my friend where changing (takes about 10 minutes). I peek over ever so often but then i forgot to for about 5 minutes. I think my hamster is pregnant she is eating alot,nesting by the water bottle, and being aggresive toward me. Weight wont matter cause she is already fat and has been. Her stomach isnt hard but it has only been 3 days, and she is to fluffy to see her nipples so do YOU think she is pregnant. Please dont be rude i didnt want this. AT ALL!

• Answer:

  Your hamster is too old to safely deliver a litter. If she really is pregnant there is a high risk of complications. It's far too early to tell, you will know for sure in a couple of weeks.
