My period usually comes when exected, maybe 1 day late and when that happens I get cramps and spotting. I've being eating more than usual including stuff that I used to dislike, for example eggs (sometimes I wake up very early or in the middle of the night feeling hungry)and all I want to eat is eggs and sweets. My sense of smell have gotten stronger. I have nauseas, and sometimes I feel lightheaded. I go to the bathroom a lot. I'm always tiered, and sleeping. My body temp is higher even thu is always cold in my house. Everything boders me and I have a lot of mood swings which is not normal in me. Are those signs of pregnancy, am I pregnant?

These are signs, only a pregnancy test will tell you if you are pregnant or not. Of course it is normal not to be exactly on the same day, so 3 days is not really enough to know , and something you may learn is more normal

So how long should I wait before taking a home pregnancy test

5 days now!! I'm taking a HPT tomorrow
