Help !!

Sophie

I have had really irregular periods in the past, but think this was due to having the contraceptive implant. I've recently had that taken out and bled heavy for a few days. I've now stopped bleeding completely and haven't bled for days. Normally when I stop bleeding and have sex it starts it again but I've had no bleeding or spotting for nearly a week. I have been having unprotected sex with my partner. We aren't specifically trying for a baby but have said if it happens it happens. But I do kind of want a baby now and have been really excited about it. I have took a pregnancy test that came back negative. But I've been feeling really tired recently, backache, bloating but test has come back negative. Is this because I am taking a test too early or I've got too much hormone someone please explain to me because even tho I am a woman I have no clue 😂😂
