Additional meds after BFP

Hi. Had unexplained infertility and used Clomid and hcg trigger. Has anyone else who used medications to get pregnant and had gotten their bfp been put on additional/new meds? Went to my first visit today...not to see the baby (way too early for that) but for 'medication teaching'. They have put me on Lovenox injections, Medrol and metformin! And continued progesterone suppositories. All until further notice. They said its for precautions. I feel like it's overkill. Anyone else????
