Help! Long one please stick with me...

Okay so...

I had my period 2 weeks ago, it was a few days late and lighter than normal but it happened and I did a pregnancy test that was negative.

Since then my boobs have been killing, mild gripey cramps etc. I was due to ovulate today and we had sex last night and the night before.

Anyway woke up this morning and was bleeding. At first I thought it was just spotting but it’s enough to warrant a pad...

Anyone got any advice or had similar? Just a bit confused!

My period isn’t due for 2 weeks.

Thanks xx
