Idk what to do

I took two tests that were blue ink and got positive I know everyone says they have Evap lines and so on but most Evap lines I saw were skinny but I've taken 4 frer at different times I got negatives but this morning after 3 minutes I swear I seen a faint line I held it up to the light and compared to the negatives but I went to take a picture about the 10 minute mark and it was gone. I have a bicornuate uterus so it's not easy for me to get pregnant. My period was supposed to be here last week. My nipples are slightly sore (although they do that on my period too) I've been nauseous having cramps and sharp pains. I've been peeing a lot more than normal . I don't have insurance yet so I can't go into my Drs. But I've also wanted this , we've been trying for over a year. My birthday is tomorrow and my anniversary is next Monday. I'm trying not to get my heart broken but I fear it already is because of all the negatives getting me down
