Hi everyone, I’m looking for some advice ASAP! I’m 20 years old and my boyfriend and I have unprotected sex… my period was late towards the end of last month. (It usually starts right on time.) a few days pass and I had extremely minimal spotting for 3 days. That was it. I took two at home pregnancy tests from First Response; they were both negative!! It has been three weeks and I have experienced nausea, vomitting, cravings, headache, tiredness, aching stomach and breasts. My symptoms are on and off, not all constant. But all frequent. I took another First Response test today and it was negative. I think that I am pregnant but do not know what steps to take next… I would prefer not to take a blood test (but I will if I have to). Does anyone know what could be happening, or have experienced the same thing?? Thanks!
