Idk what to think

So for the last 7ish weeks I have felt super weird. I’ve been feeling bloated like my period is going to start but it’s everyday. I’m an emotional roller coaster and easier to set off in one mood or another... plus wanting to cry at the smallest thing, which I don’t do cuz I’m not a big crier anyway. I’ve noticed that my boobs are slightly bigger and feel heavier, my nipples are slightly darker too. I’ve also had pretty much daily nausea, exhaustion, sensitivity to smells, and aversion to certain foods. Over the last two weeks I’ve started having crazy dreams which I’ve never really had on a consistent basis.

I also have an increased pain in both my hips and my lower back. Overall I just feel weird and the best way I can describe it is like there is a weight in my low abdomen, and some of my clothes not fitting when I haven’t changed sizes.

In November I have 7 days of super light bleeding and December I had three days of super light bleeding and three days of spotting. Which is completely abnormal for me cuz I’m usually a super heavy flow.

So far I’ve taken 8 pregnancy tests and all have been bfn...

I’m not sure what to think. I do have an appointment scheduled on the 29th.

Any thoughts?
