8/9dpo

I'm kinda confused. This cycle has been extremely different. At 3/4dpo I experienced severe shortness of breath and acid reflux.

At 5/6dpo I started having lower back pain and twinges on my right side and mild pain in my breast, also extremely tired. As from yesterday I started feeling nauseous..like I feel hungry but I can't eat, seems like I lost my appetite though I'm really hungry. I'm between 8/9dpo today and I'm still not feeling well my lower back hurts, cramps in my uterus come and go, my boobs hurt a lot and they're really sore and hard. Still nauseous and can't get out of bed.

Anyone experiencing the same or maybe had their bfp while experiencing these symptoms?

*PS. I dtd a day and a half before I got my + ovulation test
