Could I Be Pregnant?

I've had two period last month, one around Dec. 4th that solitary lasted almost a week or less. I have unprotected sex with my boyfriend Dec. 26th. Then on Dec. 28th, I have my period again, single heavier and more cramps and aches contained by my lower abdomen that last about a week. I'm mode of worried that I might be pregnant, and I really want to find out if I am or not. I want to take a Pregnancy Test, and most imagined I will. Can you be pregnant while you have a spell? I thought it was pretty unlikely? Has anyone ever be in this situation? Also, I be wondering when you start to gain weight from pregnancy, and when you will show. Thanks! You can't own a period when you are pregnant. I know that abundantly of people claim to know of someone who did, but it is not physically possible. What you can hold is light bleeding from the pregnancy that some women mistake as a extent. If the bleeding was heavier and have more cramps than normal, after you are not pregnant. You really need to gain some reliable bc instead of having unprotected sex. It is abundantly cheaper than a child is.
