Help I’m not sure

So I’ve been trying for 7 whole months now! And since last Monday I was feeling nausea, and I’ve had heart burn since last Monday! I’ve taken several test the very first one at first glance was negative then after about 40 mins (yes I know evap lines) it had a VERY FAINT POSITIVE LINE. me thinking it was a evap I didn’t bother it. I took another that next morning with clear blue. Nothing but my friend swears she seen a faint line. I took one 2 days ago took a nap checked it and it had the same faint line. Heartburn has continued, headache, tired all the time and my period is 9 days away. Someone help! I don’t want to get my hopes up
