Hi, 20 days ago I had my first round of AI, I have taken 4 pregnancy tests in the past 10 days but it is coming up negative. I am experiencing nausea, tiredness, headaches and bloating. None of these symptoms are common occurrences in my everyday life before my AI, I don't know if I am pregnant or not, I have another scheduled AI for a few days time but would like some advice, my headaches are normally lasting a few hours a day and I feel nauseous on and off throughout the day. Please any advice would be appreciated!
