Charlottee: Since the symptoms you are experiencing are not usual with you, you might be pregnant. I would recommend you tot ake the test with first response kit after 2 days if AF dont arrive till then. Till then, have more fruits and salads that will keep you healthier and away from nausea. Avoid pineapple and papaya, but have more berry fruits.
I've taken a home pregnancy test and the result was negative, this could be because I took the test quite late in the day, so my HCG levels weren't at their best. I'm going to take a second test with my first pee of the day tomorrow morning. Still not showing any signs of AF arriving just yet and I usually come on my period a few days early. Thankyou all for your advice, I will test again in the morning :)
