clomid update

So I took 100mg clomid starting on cycle day 2-6 for the first time last month my cycle was on from the 16-20 of January I took clomid on days 17-21 of January I tested and got a dark and faint line showing positive I tested again it said negative but my cycle is late and I have no signs of it as usually I feel very sick and light headed the passed few days idk if I'm pregnant are my mind playing games I called my doctor and they said wait at least 4 weeks before I get blood work done ughhh I hate the waiting process but fingers crossed praying this is it for me and my hubby
