Please read! 2 months late

I am always very very regular, but I have now missed 2 periods.

I have taken 4 pregnancy test (clear blue/first response). They both came up negative although I thought I saw a very faint line on the first one but obviously not.

Symptom wise, I’ve suddenly appeared in tiny spots on my body which I don’t usually suffer with, I’ve been sick many times, my boobs have been hurting along with mild cramping.

We have been trying for a baby since August and now I have no idea what’s going on!

Has anybody else had similar experiences? X
