3 faint postives / 1 neg

Em

Hi,

So over the weekend I have taken 3 test. 2 were first responses. The 3rd was a clear blue. All 3 have faint lines.

Throughout the night I had been experincing pain/pulling on the left side.

Then last night I started spotting. This morning it is brown/pink and is abit more than spotting with sharp period like pains. This morning I also took a clear blue digital test just to make sure and it said not pregnant. Arrgg I am so confused and feeling abit upset ! This will be my 2nd AF since being off Bc so far the cyle has been 35-37 days.

Could this have been a chemical pregancy ?
