Aimstick Pregnancy Test 16 Dpo No Sign Of AF And BFN!?

16 dpo no sign of AF and BFN!? - aimstick pregnancy test

Today is Monday and I am 16 DPO. At first I thought I had my period on Friday (12dpo), predicts the fertility friend, he would on Monday (15dpo) - but it seems that both are wrong. My temperature rose to 98, but then on Monday they went to 97.3 - still above my benchmark (97.1). He was sure that I had my time ... but no. When I got my morning temperature was 97.6 and gave me a negative pregnancy test aimstick. During the last 3 days I did not feel that something happens in my uterus, but now - I can feel pinching on the right side and a dull feelling around my waist. I read that time, if you do not 16dpo and pregnant. Others say 18dpo. If my temperature has dropped, but remains above my study that is good or bad? If I'm pregnant, I will) hold in a position to warm the baby at a temperature of 97.4 (average? Other things I noticed: thirsty, urinate a lot, hunger, mild nausea.
Thank you!
