Progesterone 200mg

Ashleigh
So i am 6 weeks preggo and I had blood work done the other day and found out my progesterone levels were low. I was advised you should at least be at 11 and mine were at a 6! I was prescribed oral progesterone capsules but I have to insert them vaginally. I took my first dose last night and woke up in the middle of the night with really bad upper abdominal pains. Also, this morning there was a very light pinkish reddish color on my pad. The color of the discharge was about the same color of the pill so I don't know if I'm bleeding or if it's just the pill. I am also having cramps and bad lower back pain. Has anyone had this experience? Please share! This is my first pregnancy and I'm trying not to totally freak out!! Thanks
