Hi im 26, me and my boyfriend have been having unprotected sex trying to get pregnant. we had unprotected sex the 17, 18, 19, and 20th. my period is due on the 23. i have a regular cycle and my period always lasts for 5 days. im not stressed or anything. I got my period on the 23 but it was heavy for the first 2 days and than stopped, than it was just a lil spotting that lasted maybe half a day. now i always feel like i want to throw up and sometimes feel sick.. could i be pregnant? i am going to take a hpt but i just dont know how long to wait before i take one..
