Hey all, I've just found out I am pregnant after 5 chemicals, the first month after 3 months sitigliptin for low NK cells and progesterone post ovulation (so far so good). Had really strong implantation symptoms (cramps, nausea, sore boobs) and everything tailed off around 16dpo. Obviously my anxiety is through the roof and I'm looking for reassurance and advice. Easy at home tests processed well 12-16 dpo but the last one at 18 dpo isn't getting dark enough to ease my worries. Probably nothing will! Anyone been in this boat with stalling tests?
