Pregnancy and periods

Kait

Hey girls. So my husband and I are both in the military and are stationed separately right now. Well we decided that we want to try for a baby during our leave on Christmas (19th-3rd). However, I’m supposed to start my period around the 28th. Is it even possible to conceive that close to my period? And if I do, would it be likely that would have a period of at least a little spotting? I’m terrified of not being to get pregnant.
