I had my implanon removed exacly 4 weeks today. I had a period the next day ater removal for about 4-5days estimate. It was painful too much, im currently trying to concieve i havent had a period since then. I have had unprotected intercourse since these 4 weeks. I have done tests but all negative. I have been experiencing a few signs like stomach gurgling at night time, butterfly feelings and back ache and feeling sick and struggling sometimes to swollow food it makes me gag. I need some advice, can i become pregnant really quick?
