phantom pregnancy

I gained two weeks in a row! :( I have had other gains along the way but this is the first time ever two weeks in a row. Thankfully I didn't make it three and I was down this week, (although not as down as I had come up) My period is also totally out of wack, (3 weeks late now!) but 4 negative preg tests should have me convinced its not that. still confusing. How long should I wait before I go to a doctor? bearing in mind that this is totally unusual for me, and also hat Im living in a foreign country where going to the doctor is not just easily done.

FINALLY back at water areobics this morning, which felt real good, I also went friday. They closed over the holidays which I'm sure also contributed to two weeks gain. And our daughter did not have kinder those weeks so there went my 2 half hour walks to drop her off and pick her up. plus all the new years candy ;P

Gonna buy a new swim suit when I get to 80kg.
