20 days late advise girls, im going crazy

Okey. Going to be a long one.

My AF has started right on time. Every 30 days for as long as I can remember.

My last real period was on Nov 9th.

I Bd( baby danced) during ovulation on the 24 last month.

On the 10th I started spotting. Only spotting. Needed no protection. This lasted two days.

Over the past three weeks I have taken 3 hpt test. All negative 😒

But my Body is telling me something completely different. I'm sleeping about 15 hours a day. Pure exhaustion 😴

I'm Bloated. So bloated I went to Dr. (Clinic)

They told me I prob have colitis/ indigestion issues and just gave me a bunch of meds for the bloat and gas.

I did tell them about my monthly and they did an urine hpt (negative).

My boobs feel so heavy. I don't want them to be mine. My nipples are tender and hate a bra.

I feel like complete crap. Also I have been told Clearly by my Fiance that I look like death..😢 of course made me cry. Plus the back cramps.

I guess I just want this all to be over with.

Either start a good strong AF or get my BFP so I can embrace this crappy feeling.

So anyway my ? Is. Do you ladies think it could be possible for me to be pregnant? And just not be far along enough. Or am I driving myself mad for no reason at all?
