I’m 9DPO and for the last 4 days have been getting heartburn/reflux several times a day. I have also been feeling a bit crampy daily and had 1 episode of feeling very nauseous on Monday evening. AF is 4 days away, no spotting and 2x BFN on cheap tests yesterday and today. Aware reflux could just be due to hormones pre AF but i’ve never had it before as a PMS symptom?! Has anyone else experienced this as PMS or pregnancy?
