Ok so I extremely lost and confused. So last night I decided to take a test because I am having NO pls symptoms at all which One always do before she shows and it came back positive while it was drying and my husband saw it too. Then it turned negative after it dried. Last month almost same thing happened, but I had a faint and turned chemical. Also had pms symptoms. 10dpo. Should I wait and test again? Also this app says she's due the 9th and fertility friends says the 15th. PLEASE HELP!!!!?
