I think I'm having a cryptic pregnancy?

Hi ladies yes this sounds batshit crazy. I know.

But basically I had a chemical pregnancy (I was a week late for AF 3 weeks ago got faint lines then "AF" came) I tested on the last day of bleeding and my line was darker.

Let me add my bleeding wasn't clotty, I had no cramps either. Just bright red fresh blood.

Anyway, I assumed chemical pregnancy as I've had negative tests since then.

However, I've been having waves of nausea, no appetite but my stomach is beyond bloated, sensitive nipples and today I'm having a lot of pressure down below (I feel like my cervix is going to drop on the floor) and it's become extremely uncomfortable.

I carry a little extra weight anyway but my lower belly feels hard from bloat. I've been pregnant twice before and I have never felt like this apart from when I've been pregnant.

The pressure like my whole uterus and cervix will drop out is actually concerning me. I am going to go to the walk in centre tomorrow.

Seriously what are the chances of still being pregnant? I would be 7w1d since my last PROPER period.

I've read all these stories about women not knowing etc but I literally feel pregnant HPTs are just negative I have no idea what's going on. Any advice/help/stories welcome!
