I've been trying to get pregnant since June with my partner. We had a positive in May but lost it. After that we had lots of very faint line positives only to then have very light periods. Today I had believed to start my period but for some reason the blood was way lighter(typically have very heavy periods) an then completely stopped in the same day kind of pinkish but idk what it means. 2 days prior I took pregnancy test and it said negative idk what to do and this is my first time trying to have a baby. Please help me understand
