Hey ladies so i am about 7dpo and i notice my nipples are sore, normally if its due to period coming it would be my entire breast sore but this time its only my nipples they are sore and very sensitive. I been dealing with severe heartburn at night, also had spotting two days ago along with cramping. When should i test? I tested two days ago it was completely negative. 7 more days my period is supposed to come. Thank you ladies.
