Suggestions?

Ma

So I took two pregnancy test and one had a faded line in the background so I took another one, that one came out negative... But the weird thing is , I still haven’t started my period. Could those be false negatives or is there something wrong with me? My boyfriend and I do have unprotected sex a lot but I don’t feel pregnant. My friend tells me i’ve been acting strange lately but i don’t know. What should I do ladies? 😓😩
