Well I just went through Invitro fertilization 2 weeks ago I need help with these symptoms I'm experiencing

Well as you have read I've had IVF done 2 weeks ago. The beginning of the first week, I got really dizzy and oh my lord my are in so much pain. Are these symptoms psychosymatic or what. I've been pregnant 3 times before and I've never experienced such a thing. Constantly going to the bathroom (I'm like a freaking fountain it's embaring at work too many pee breaks), tenderness (never even had it during my periods nor before my periods) Even my shirt kills them. Constipation, back ache, I had all of these during my second and third trimester. Is this just a side effect of the procedure. If anybody had a positive result with IVF please inform. If you're wondering why if I've been pregnant before, do I go and perform such procedures. 2nd marriage and my husband has low sperm count so we needed technical help from the doctors.
