Feeling terrible! Need advice.

Sabrina🌸 • 🤵👰7/25/15 👧🏼12/6/13 👼2/21/15 👦3/26/16 👧6/27/18 I`m 26 and have 3 beautiful babies! Due with #4 September 2020

Okay so this morning I took a pregnancy test and it came back positive. I was definitely not expecting it. My son is 4 almost 5 months old. Well before I found out I continued to take my pill and I also donated blood last week without knowing. I feel terrible. I'm going to the doctor today so I will inform them as well. I am so upset with myself. If I had known I wouldn't of done any of that.

EDIT*

Went to the er and come to find out it was a false positive! It was positive because the cyst on my ovary popped.
