I ovulated last Wednesday. Ever since then I've been experiencing random short bursts of cramps, awful nausea to point I'm dry heaving at random points, massive headaches and intense itching on my back arms and stomach. I've also had a weird sensation on my tailbone when sitting for a long time. I wouldn't say this is pain as such more just uncomfortable and I have no bruise and haven't banged it. I am also frequently urinating and more thirsty than ever. Is this wishful thinking it could I possibly experience symptoms so early on?!
