Pregnancy Info HOME

Okay, I have two questions. First one, is could I be pregnant? My boyfriend and I had s_x for the first time since we've been together on Oct 5th and 6th. Then, we had s_x again on the 19th of Oct. We had s_x probably ten times total from the 5th, 6th and 19th. And my period was due on the 23rd, but it was three days late, I brought a two pack of pregnancy tests and I took one and it said I wasn't pregnant, but I decided to wait the three days it said to wait and try again, but before the three days were up, I got what I thought was my period, only I didn't cramp, I didn't have hardly any moodswings like I normally do and it just seemed different. It was like a normal flow though, it wasn't light, but it wasn't really heavy. It was just kinda normal. So, my boyfriend and I just decided that I wasn't pregnant. We didn't have s_x again until this past Saturday (Nov. 3rd) but I've been having what seems like alot of pregnancy signs. I've been getting alot of morning sickness, I've been dizzy, I've been craving food like chinese and pizza, in fact I just had a craving right now for a Burger King Double Stacker and I just ate a snack not to long ago. And I've been having va___al discharge alot...I took the other pregnancy test this morning and again it said I wasn't pregnant. Can someone help me? I'm going back to my boyfriends hometown with him after Thanksgiving, I'm thinking about going to see a doctor then. And also another question me and my boyfriend were wondering about, is it safe for him to c_m inside me if I am pregnant? Will that effect anything?
