My cousin is very late for af. 2 weeks to be exact. She's taken 3 poas tests all with negative results but she is still experiencing pg like symptoms. She gets light headed, nauseous, is very tired. She is having sensitivity to smells and touch (particularly on her breasts). She went to her family doctor and she said that her heart rate was pretty elevated, but my cousin has a heart condition that can cause this. She asked the dr. if her heart condition can affect af and the dr. said it shouldn't but being pg could trigger her heart condition. So the dr. recommended that cousin get on prenatals because she needs the vitamins anyway and they took a blood sample to test for pg. and scheduled her to come back next Wednesday for an ekg to evaulate the heart. Her dr. is out of the office until next Tuesday so she won't be able to find out the results of the blood test until then.
Long story short: Do you think she's pregnant? What is the likeliness that 3 different poas test from 3 different manufacturers were all bad? Has anyone completely missed af due to sickness not pg?
