Think I’m having a phantom pregnancy!

So Iv had some strange stuff going on lately. I started having pregnancy symptoms identical to the ones I had with my last pregnancy. But I’m on the pill and have been having my withdrawal bleeds. I did a test a while ago and I thought I saw a very faint line but the next few were negative so I thought no way. Well I’m still having symptoms. Cramping, discharge that looks like mucus plug, change in taste and smell, feeling ill after eating, fatigue etc etc. Well tonight Iv all of a sudden got a bump! 😱 I’m so bloated I look pregnant. And I don’t mean like all the girls you see on here posting pictures of their “bumps” ans nothing is there cos they’re only 3 weeks pregnant! I look like I did when I was like 15 weeks pregnant! What’s going on??!!
