Pregnancy worries- reassurance needed

Last week I experienced a small amount of very light brown discharge. I think it was after a bowel movement  and had no cramping. I was reassured by my midwife that it was nothing to worry about.

I'm now around 11weeks and after exercising last night I once again experienced two very small spots of light brown discharge. Once again called a midwife for reassurance- except I didn't receive it. I was told that it could be a possible miscarriage or ectopic pregnancy and in being sent for an emergency scan in the morning. She also laughed when I'd told her I'd been exercising. I haven't had any further brown discharge.

Since about lunchtime today I've been experiencing some mild pain to the left of my belly button. More like trapped wind than anything like period pains. Lay down now and it feels like it's subsided.My stomach is also making a lot of gurgling noisies. I suffer with bouts of IBS which tends to flare up when stressed. However I'm terrified that it is perhaps an ectopic pregnancy! Has anybody experienced anything similar? Could do with a little reassurance! I'm going out of my mind with worry and read some scare stories online.
