So my husband and I have been trying to get pregnant for 2 months now and nothing but for like 3 weeks I am hungry every 2 hours and I get a little nausea. So last Wednesday I was suppose to start my period but didn't and still haven't. I also took a pregnancy test the day I was suppose to start and it was negative. I get very uncomfortable laying in bed it hurts to lay on my sides. What do you guys think? Should I retake a test soon or wait a little longer?
