Hi everyone so I’m 15 DPO and I am curious if anyone has experience something similar to my situation. I’ve already taken a couple of pregnancy test a while back maybe 5 - 7 DPO and I got a negative result. I’m not sure if I should test again or just wait a little longer till I get my period . Ladies please I’ll appreciate if anyone could help me out or give me advice. I really want to have a baby as well.
