Pregnancy test question

So i had a m/c on the 9th of may obgyn said take it easy and use condoms wich we did but one broke. I didnt even think i would ovulate. Not even sure if i did. But im 4 days late for my period and so i took a test. Forgetting about it i checked it about an hour later and found this. Sence its been so long can i even rely on this? plus its very faint. Any suggestions?
