Last regular period (usually 4 days) was in June and then July it came for one day on time took 4 test and all came out negative. Now this month period came on time on the 1st but that was the only day I bled and now my boobs seem bigger and hurt when touched and they never hurt. Before I run to waste money on a test I want yalls opinion. These one day periods are throwing me off and I haven’t done anything different from June to now.
