Am I pregnant??? anyone with experience with Clomid??

Melody
I am so confused. I had my period February 5th and it ended February 10th. I started taking birth control February 12th,because of my doctor said it would help with my breast lactating even though I'm not pregnant, but I only took it for a couple days because the side effects were so bad. My boyfriend and I had unprotected sex the February 11th, 12th, 13th and 14th. We basically have sex every weekend plus mondays.
I had a hormone panel done on me around January 19th for hyperprolactinemia and she said everything came back normal. On February 20th I got this intense abdominal cramp and it knocked the air out of me, I went to the bathroom And I seen that there was a light brownish-pinkish discharge/blood. The discharge came and went for a few days. And I also missed my period for the month of march but my periods go through phases where they are normal and when they are irregular. 
Lately I have been feeling nauseous and having morning sickness and I even threw up a couple of times but I'm unsure if I am pregnant? I'm experiencing symptoms like frequent urination, mood swings, sore breasts and sensitivity to certain smells and foods that once wouldn't bother me. 
Do you think I am pregnant? 🤷🏽‍♀️
If I'm not pregnant, my doctor mentioned giving me Clomid, do any of you have experience with it? If so what was it like? And how does it work?
