POAS in a week???

Hi everyone!

My husband and I have been trying for a baby for over six months. (Tho for the six months before that we weren't trying, but not preventing either.) I tried doing the BBT thing, but it was hard for us to do because of varying schedules. With my cycles being so irregular tho, it's hard also to judge when O might occur. This month tho, we've just BD'd a lot...

Now, the 'average' of my cycles is 39 days. (Prolly only because I can't remember one of my periods, and I didn't chart it because we were in the middle of packing for a move.) I am due for AF July 21 for a 39 day cycle.

I have been having 'symptoms' that are not normal for before my AF. I have been having terrible nausea when I first wake up. I've been extremely exhausted. (Going to bed early a lot, and today after doing some grocery shopping, had to take a nap, etc.) I normally get terrible acne before AF, and now it's just normal for during my cycle. Oh, and I normally have extremely sore breasts, and very sensitive nipples, and I don't have that at all!

Every time I go to the bathroom, I check, and no sign of AF. But I have tested twice and gotten BFNs both times. I tested using the Answer early result tests, and am thinking I should try the Dollar Tree test when I test again. I was also thinking I should wait until next weekend before I try POAS again. What do you think???

Thanks for your opinions!

(P.S.- My husband's dad just passed away in May, and if I am pregnant this time around, the baby's due date would be the day after my late fil's birthday... My husband really likes that idea... =0) I hope to be able to tell him that his wish will come true!)
