I have major stress... I have always had periods that last 8 days, now recently they have only been 5 days.

I have been on Petogen before then stopped using it for a year. I have had sex when I was not on the Petogen, and have taken many urine tests and they have come back negative. I recently took a blood pregnancy test a couple days after an odd short period. (odd for me because Im used to it being long, even though the flow was very heavy at first and deep red. Sorry about the TMI) The blood test came out negative, but my tummy has been bloated but slightly hard. I then proceeded to have the Petogen injection days after the period. My breasts are ok, they were insanely sore a week before my period (which is normal) I have not felt nauseous, or vomitted. Nothing is different except for this hard bloating. Did I take a blood test too soon? Should I take another test? Could it be the Petogen is making my tummy like this? I have not been eating as well as I usually do, and I have gained a bit of weight, but still fit in my clothes, and I know your breasts grow when you put weight on. I'm so stressed, and taking all these HPTs are driving me insane, I'm constantly thinking I'm pregnant...

Any help would be great
