I feel pregnant! Help!

Hiya ladies,

So a breakdown, my last period was on 7th May, a day or 2 I had unprotected sex, then came on period, after finishing period, I had unprotected sex again and then I had the implant put in, my gp told me to wait atleast 2 weeks before we had unprotected sex, but we didn’t 😩 anyway I’ve been having pregnancy symptoms, tiredness, nausea, shortness of breath, I’ve done pregnancy tests and all were negative. I’m getting a blood test tomorrow. Has anyone had any similar experiences, but then found out later they’re pregnant! Also I’ve heard from others that blood test didn’t show up as pregnant, but they found out they’re pregnant later! Also, I feel these movements in my belly and trust me I’m not bloated or anything , I have a child so I know the difference. I feel pregnant. Anyone had similar experience? Please let me know!!

PS: I don’t get period symptoms. Also if I did, I’d know the difference between them as I’ve got a child and this will be my 5th pregnancy, but it’s the first time this has happened to me.
