Ok, so lately I've been cramping, but it doesn't feel like I'm the normal spot I usually cramp. Also have really sore nipples and tender around them. I've been feeling in &I off nauseous, but idk if that's me over thinking or actually getting sick. For example, I was in the pet store yesterday and walked past the hamsters and almost puked. I grew up with hamster and guinea pigs so the smell has never bothered me before. Also was getting it around 630 every day for a few days and then woke up this morning a little queezy. I usually get my period around the 17/18, but with February missing those couple days, I think it should have been around the 20th or so. I spotted about a week or so ago once but that was it. No sign of blood since then. How long should I wait to take pregnancy test?
