What could this vaginal discharge mean? [TTC]?

Me & my partner are trying to have another baby since we lost our first little girl at 5 months, three years ago.

I've been off of birth control since April 22nd & I stopped an about 30 day bleeding cycle on the 27th.

[It was scary, I almost needed a blood transfusion.]

Anyways, about a week ago I started cramping really bad & getting sharp pains on either side of hips kind of. Those pains have since gone but that is about the same time I started having this white discharge.

It is a milky, white discharge that has a lotiony texture to it. It does not stretch at all like a mucus discharge would and it has no smell at all. After about 4 or 5 days of that it just suddenly stopped for a day, or at least got very light. Now it has started up again only it is alot heavier & I've had to wear panty liners.

I have been excited because I'm thinking this could be the first sign of a pregnancy but the texture has not changed.

Can someone please give me a personal experience of some sort?
